  1. Block was hot tanked. the deck was surfaced by only a few thousandths 2 or 3. Heads milled .010 did not enlarge spring pockets they are stock. Head gaskets are Felpro FEL-8518PT. No sealer on head bolts. Pontiac do not need thread sealant since the bolts do not break into the water jackets, did lube them. I did all the assembly myself. I'm feeling like there must be a blockage of some sort inside the block. I'm gona get my buddy's infrared thermometer and check different ares see if I can find any hot spots. I'm really running out of ideas. Maybe the Gen3 just won't let enough air pass

  3. Two Lane try the file I just posted "1.ts"
  4. Let me see about changing video format, brb
  5. Two Lane, Use VLC player and you should get sound I spend alot of time under the hood hence the need for the gauges. Took it out shortly after the video, runs like a scalded dog but still getting hot. Was running 60 and temp climbed to 230. Shut it down and sat for 30 minutes before I headed back to the house. Almost 240 by the time I get back. SCARY
  6. Two Lane, pretty good. The space between the shroud and rad core is somewhere around 1 inch. Maybe not enough. The shroud came with the rad. I should be done with the exhaust tonight. I ran out of Argon the other day and you know how bad the splatter is without any shielding gas....
  7. Frosty, The shroud is aluminum and flat. rad2.mp4
  8. Two Lane, Good thought, the lines coming off the adapter go up and over the bell housing towards the left then under the steering shaft wrap around the inner fender well going towards the front of the car and the filter is mounted on the front of the fender well. You can see in this pic the right side exhaust is not close to the lines. But I may be on to something, it doesn't make a lot of sense but. I had to cut out my muffler in order to replace the gas tank. For S&Gs I fired it up without the muffler and it never went over 195. BackPressure to high? It didn't appear that way. New muffle
  9. Two lane, I agree 220 is not overheating with a 16lbs cap. If it didnt rise above that I'd be ok with it but it keeps climbing and climbing, slowly. I haven't had a chance to install the 195 stat yet, maybe tonight. Charlotte would be a 11 hour round trip for me, I'd like to go but its not likely this year. Any way I had to replace the gas tank due to trash in it also installed an intank pump and aftermarket gauge sending unit. Hopefully I can take it for a spin tomorrow. OldGuy, I made a mistake about the pulley its a 6 1/2 inch. As far as antifreeze goes it has 1.5 gallons and somewhere
  10. Frosty, yes the lower valance and the air dam are both in place. I installed the FlowKooler pump and it still overheats, although not as fast. Previously it took about 20 minutes to reach 220, now its 35-40 minutes before it reaches critical temps. I have a 165 degree thermostat in right now and I am thinking the water never stops moving as the stat never closes, my thought is its not staying in the rad long enough to transfer the heat and cycles hot water right back into already hot engine. So I'm going to try a 195 stat hoping to slow down the flow. Still open to new ideas......?
  11. Old Guy, when I say it is "rich on purpose" I don't mean it is so rich that it is blowing black smoke.. But more to the rich than to the lean side of things. As far as the timing marks go, my timing cover does not have the casted marks and I didn't have a bolt on timing pointer. So what I did during assembly (heads off) is bring it to TDC then measured the degrees I could rotate the crank before the piston starts to move and then centered that, then marked the timing cover matching the mark on the balancer. I'm pretty sure I am with in 1 degree of being dead on TDC. Back to overheating,
  12. Frosty, your right about the pulley that is something I didn't even think about. The crank pulley is stock and water pump pulley that is on now is 4" diameter and factory (if I'm not mistaken) is 6-1/2", So I'm over-driving as it is. Yes new heater core to indymanjoe, Lower hose isn't collapsing, its got the spring. Also I never seen one collapse at idle but I guess it could if it were old and soft Rad inlet is hotter than outlet by about 25 degrees so there is some cooling happening just not enough to counter what the engine produces bad pump?? even though its new, tha
  13. hey guys, its taken a day to get back to ya. Frosty, yes new flow plugs and divider plate, plate clearance set to a minimum Two lane, your probably right its something stupid simple getting overlooked, wtf is it lol Frosty, wouldn't over driving the water pump be like a band-aid? if it even worked. please dont take any offense to that, I appreciate you throwing out ideas. that's why we're here, right? Two lane, you mentioned something about a fresh engine post, I am interested in reading it. where can I find it? sorry if that is a dumb question again thx for all
  14. Guys thanks for taking the time to put thought into my problem Fresh engine yes, maybe 10 hours the air dams are in place 100% fans are moving air the correct direction I did check for vac leaks, none. Also I have it running way rich on purpose I don't see a lot of value in that burping funnel thingy. If air was trapped in a cavity I see no way that device would remove it any better than just taking your time purging. Not that I don't appreciate the idea because I do, thank you. Just being honest New water pumps are not always the right water pumps, I think I'm le
