  1. The pump is the one that was on the engine when it came, probably not the original but the original style. I don't know for sure that it is one of the lead plugs that is leaking, I am hoping that it is because that is a repairable problem as opposed to a crack which is not. If it is cracked I have no idea where I would find another one of those carbs or at what price, and finding a four barrel manifold for it is even more remote. I am aware of the thick foam gasket that was available for the Q jet, I used many of them but found that after a little time the gasket would shrink and the problem would return. I found that popping the plugs out turning them upside down and gluing them in was a more permanent repair. It has been so long that I do not remember what glue I used but something like JB weld would certainly work. I would file off the sharp edge of the plug so I could drive them in up side down without gouging the hole. I would glue the plug and hole and tap them in. Once in I would very carefully take a punch and hammer and tap on the plug to expand it, similar to an expandable freeze plug in an engine block. Using that method I never had one of those repairs fail. The only issue is that you must use extreme caution because if you expand them too much you will crack the carb and then you have an ugly paper weight. The 2GC is a completely different animal so when I get time, get past the family issues, I will take the carb off and apart again set the float bowl up on something fill it with gas and wait. I wonder if I could put some red food coloring in the gas to make it more readable. If it is one of the lead plugs I have many times used the right size lead shotgun pellets as a replacement plug. drill out the old one, a little glue one pellet and a small pin punch should do the trick. Just wondering if you have ever heard of Howell Engine Development in Michigan. They have a plug and play 80-90's vintage GM TBI for the engine which is another possibility. The only problem with that is the family problems which in addition to sucking the life out of me are sucking the life out of the bank account and right now there ain't any money to buy one. Hope that your issues are soon solved.
  2. OK, I think that I am getting closer to some answers. I mentioned in an earlier post that the plugs on the high runner are reading richer than the low runner. I was out of town for 11 days and when I got back I went to run a few errands. I tried to start the Pontiac and it would not light. I kept cranking and pumping the pedal and it finally lit. The carburetor was dry. There is a leak somewhere that I have not found. I have had this problem with more quadrajunks than I can count but never with a 2GC of any kind. Guess I will need to take it apart again put fuel in the float bowl and wait for the leak to appear. A 54 year old carb, I hope that it is just a loose lead plug in one of the passages. The garage has had a raw gas smell from day one after driving it and parking it in the garage with a warm engine, might have found a reason.
  3. I understand completely. I have been dealing with a family tragedy this week, no one died but that is the only thing I can think of that would be worse than the present situation. this family stuff will suck the life out of you faster than your 90% humidity. Just for giggles I did jack up one rear wheel and spin it while counting driveshaft revolutions and it does appear that 2.69 is actually correct. The tires however are only 25 inches tall which is why the engine sounds like it is spinning faster than it should with that ratio.
  4. Two lane, I am finally back to the Pontiac, life and leaking fuel tank issues. Several posts ago you said that the code 2 diff is a 2.69 ratio. Was that a misprint? finally got this thing on the road and running reliably, Other things had managed to find their way farther up on the to do list than the Pontiac. Plus it took almost 7 weeks to get a new gas tank and sending unit. The only people I found that supply them were out of stock and apparently it takes a long time to have them made. I need to jack up one rear wheel and mark wheel and driveshaft and spin the wheel to get an approximate gear ratio but the way the engine spins on the freeway I would bet the ratio is closer to 3.5 to 3.7. So I have run a couple of tanks of gas through this thing and it is running good but it still sucks fuel, about 11 or 12 mpg which doesn't make sense because it takes almost zero throttle to keep this thing rolling. My friends 67 Shelby 500 KR does better than that. The carb still has issues. I have had the thing off and apart 4 times and can see nothing. All the gaskets have a good print on them and I can see no cracks or other issues. There are strange things with it like coming home and parking the car on the driveway, which has about a 15 degree up angle, if you restart it within 15 to 20 minutes it is flooded and the float level is already 1/4 to 3/8 lower than spec. With about 400 miles on it I can get a plug read, the plugs on the high runner are brown but the plugs on the low runner are white. Another thing, the exhaust is so cold on this thing that it is not even burning the paint off of the exhaust ports and the heat riser was not opening, spring too cold. I finally just unhooked the spring and let it fall open and backed the choke spring off a couple of notches. The exhaust still smells fat but the plug read would say different. Maybe it is just the absence of catalytic converters. I found a plug and play GM tbi at Howell Engine Development in Michigan which uses the 80-90's vintage gm tbi that I can bolt to my two barrel manifold. Ever heard of them? The other option is to keep looking for a 4 barrel manifold and use the Holley tbi. Or? The car runs great but I would really like to squeeze a few more mpg out of it.
  5. I have been busy with life that has gotten in the way of everything. I have seen the posts and recently found out something, electric fans do a lousy job of moving air through a thick radiator. I have a '63 Catalina that was built during GM's weird days, it does not have a temp gauge! I can have a temp (and oil pressure gauge) installed by classic instruments for around $2500.00. I chose to go another way and put in a 4 row aluminum radiator to insure that it just does not overheat. I also installed A/C. To cool the condenser I have a large electric fan between the radiator and the condenser. I said all that to say this. The A/C works well as long as the ambient temperature does not go above the mid 90's. I had a lot of thoughts what to do and figured that the easiest thing was to put a bigger fan on to see what happens. I purchased a 7 blade flex a lite flex fan and put it on replacing the factory 4 blade. Wow what a difference. I need to agree with last indian, electric fans just don't do a great job of moving air through a thick radiator. The flex a lite not only has improved the efficiency of the A/C there is a noticeable difference in the under hood temperature after a run in 100 degree temperature. It seems like a relatively simple and inexpensive thing to strip all the shrouding off of the radiator install a high volume engine driven fan and see what happens. A FACTORY type shroud that funnels air from the entire radiator without restricting flow like what you have would probably help but if the fan is close enough to the radiator may not be necessary. Seems to me that it is worth a try, after all you have been through.
  6. I can sort of make them out but lowering the float level about 1/4 inch lower than the instructions called for seems to have made a tremendous difference. If I need them possibly I can move them to another program that will allow me to manipulate them.
  7. Two Lane, I did take the carb apart and took another look at it. I had forgotten that the idle circuit on that design carburetor two and four barrel was fed through metered tubes in the main jet wells. Short story is that they are much better metered than the earlier end bowl holleys. It is my understanding that Holey has fixed all of its gremlins in the past few years but I digress. When I pulled the top off of the carburetor the fuel level looked high and with a float in it it would be even higher. I lowered the float about a quarter inch from the level shown in the instructions that came with the carb kit and went out to run a few errands. When I started it up I let it warm up and found that I needed to lean out the idle screws, a good sign, and driving it with the top down you get a lot more of the exhaust smell than you get top up and the nasty rich exhaust smell seemed to be gone. Something as simple as the float level? Anything is possible. Re: cal gas. We have the winter and summer blend. More ethanol in the summer blend. We are still on winter blend. At any rate I will drive it for a while and see what happens. I might drop one jet size and see what happens, It has 64's in it right now. On another subject I just picked up a 4 row aluminum radiator, with A/C on a 110 degree summer day in our lovely L.A. stop and go traffic I do not think that there is such a thing as radiator overkill. Question is which coolant to run. When I had the Ford diesel I switched it from the green to the red coolant on the advice of a friend that used to be a heavy equipment mechanic with Caltrans. Something to do with the egr cooler. When I did the 100,000 mile service on my wife's Lexus I put it in that and what the h... did the Mercedes SL at the same time. The A/C I put in the car is out of a late 90's Crown Victoria which has an aluminum heater core that did have the predisposition for premature failure in the police cruisers. Ford came up with a variable restrictor in the inlet hose that helped until motor transport found a source of copper heater cores. I checked and the copper cores are no longer available, haven't checked with ford on the variable restrictor yet. So with all the aluminum which coolant is the least corrosive.
  8. Two lane, IT'S ALIVE! The car is running, I have been driving it for a couple of days and the camshaft seems to be exactly what I was looking for. The low end throttle response is so good that I had to jack up the trans throttle pressure linkage because the trans was shifting way too soon. This should result in improved fuel economy and it appears that it might have but the carb still seems to have problems. What slight amount of driving I did before I took it apart it was sucking fuel faster than I drank beer in my teen years. It is still sucking fuel but not nearly as bad. It has that nasty rich odor when running but not bad enough to be blowing black. I pulled the plugs for a read but I have not had to read a plug since the switch over to unleaded fuel and am not sure what to look for. With about 70 miles on the plugs they look like they just came out of the box. In all my years I have never tweaked any Rochester carb, my carb of choice was AFB for street and end bowl Holley for performance. I know that the end bowl Holleys were notorius for feeding too much fuel when they were in the transition stage coming off of idle before the throttle was open enough to be feeding off of the venturi cluster. Is it possible that the 2GC Rochester suffers the same problem because on the surface streets the throttle is never open enough to reach the venturi cluster. Back in the dark ages we used to plug and meter the transition passage on the Holleys to lean them out while in the transition stage and I would guess that it should be possible on the Rochester if I need to figure that out, or possibly there is another answer. I went through the carb and found no cracks or warpage anywhere everything looked good with a straight edge and the gaskets that came out all had good sealing marks. I plan to take it off and take it apart again this morning to see if I might have missed anything but I don't think so. I am not too familiar with anything east of the Rockies but do not think of Indiana as having extreme elevations so I would not think that the original jetting is incompatible with the 1100 ft elevation of Oak Park. Have you ever heard of anyone converting one of the late 80's early 90's GM throttle body injectors as they were two barrel and would fit on my two barrel manifold. The two problems that immediately come to mind would be a distributor that would fit in the Pontiac that has the internals to trigger the injector and a crank position sensor. Those post date my years of crawling around under hoods professionally so do not know if they ever used that system on a Pontiac. How is the race car. Did you get it on the track for the race or chuck it and go home. Bad omen for opening day, hope the rest of the season improves.
  9. 2.69 is about what a 3.5 would be with a 700 R4 in overdrive. Sounds like it might all work out for cruising mileage. It should be ok in town also, the trans is geared low enough in 1st gear that even as sour as the engine was running it had good throttle response at stoplights. Frankly better than I ever expected for a two barrel single exhaust engine. Sorry to hear about the car but rear is better than front. A whole lot less moving parts back there. Are you going to try an all nighter to get it back on the track for the race or have you just resigned yourself to see the race from the stands?
  10. OK crawled back under and took one of those tooth brush size wire brushes and cleaned the area. The stamping is pretty faint but looks like it could be a 2
  11. Did not see anything in that location but will take a closer look tomorrow, right now I am putting my beat up body to bed.
  12. OK just rolled under there again and can find no numbers stamped on the housing. I do not think that it has been changed as it still has the lock tabs on the u joint u bolt nuts and no one ever put those things back on. While it is still up in the air I might soak it with cleaner and pressure wash it in case the stamping is faint and I missed it.
  13. Two lane, OK so I spent the whole day under the rear of the Pontiac installing the sway bar and shocks. I was wrong, it doesn't connect to the frame and link down to the axle it attaches to the axle and links up to the frame. Once I started the installation I remembered the set up because you had to be cautious lifting one of those things with a weaver twin post lift so you didn't snag the sway bar with the rear cradle. Anyway I looked for a tag on the rear end and did not see one. It may be buried under the coating of gook that is so prevalent under this thing. If you have an idea of the approximate location I can scrape some of the garbage off and see if I can find it. Assuming that it is a tag that bolted on when the center section went in I am guessing that it should be on one of the studs. If not, where?
  14. Do I remember the turboglide!! The turboglide was a takeoff on the last of the Buick dynaflow's with either a five or seven element torque converter and a hydraulically controlled variable stator. A couple of us ran a chevy on the short track many years ago in hobby class. It had a 230 six cylinder, the engine that replaced the stove bolt in as I recall '64. It was a 7 main six which theoretically gave it the capability of higher rpm's. We got the wild hair one time to try a turboglide under the untested theory that if cammed right the variable stator could get us up into the strong part of the horsepower curve coming off of the turns with hopefully better acceleration. I sat down with Racer Brown and explained what we had in mind. He gave me one of his classic REALLY! looks, shrugged his shoulders and said that it probably was not a whole lot different than a boat spinning up the propeller, and ground us a cam. needless to say it was a grand experiment that failed. Even though we were cooling the trans with a large A/C condenser the amount of heat generated in the converter shortly took out the transmission. While it lasted it did show certain promise and it was one wierd sounding thing coming off the corner. It was fun while it lasted but it did not last long. So yes I have interesting memories of the turboglide. On another turboglide note I knew a guy who had a '57 chevy trailer queen show car. It was a two door wagon fuel injected and air conditioned with a turboglide. It had to be some kind of odd ball special order as I have never run into anyone that ever saw another fuel injected chev with A/C, and come to think of it I do not ever remember seeing another fuel injected car with an automatic trans. It was all factory because he knew the entire history of the car and spent years talking the original owner out of it just because of the novelty of it.
  15. Duration at .006 268 intake 270 exhaust, at .050 intake 208 exhaust 214. Lift 427 intake 445 exhaust and yes I have given up on ever putting regular fuel into it.. As for torque converter this has the roto hydro (slim jim) doesn't have a torque converter in the generally accepted sense. It has about an 8 or 9 inch fluid coupling inside the trans that works in first gear (stage one and two) when it shifts into second gear (third stage) it is in a lock up state as it is in third gear (fourth stage). That is the reason that I abandoned the idea of a trans change. I had forgotten about that trans and as it is in a direct drive cruising there is no reason to change it. This one is low enough mileage that it works like new, or if it has been overhauled whoever did it knew enough about the trans to put his impact wrench in the drawer and hand tighten everything. If you use an impact wrench to assemble one of those things you will distort the case and the trans probably will never work correct again no matter what you do. I will be getting under the rear shortly, maybe tomorrow or Saturday, and will give you the numbers however when I put the disc brake conversion on it I will need to go to 15 inch wheels which will change the final drive marginally slowing down the engine and maybe making a slight difference in cruising economy.
