  1. Kudos to you Stewy! Most folks would or do think folks like us are crazy! But we get it, and for me that’s enough! When you put that much of yourself in something it takes on a personality, it may be an inanimate object, but really it is so much more! As long as at the end of the day we know what it’s proper place is with respect to other things, than we’re good.
  2. Started to bend up some pieces for the new plenum! What do you do when you don’t have a brake? Improvise! What else! But still a long way too go!
  3. Just what I was thinking Sprint! That’s actually what, I, would do, but I would just bore it out to the next size up and make a new piston for the next size up seals. In that way you’ll move more fluid and make the brakes even better! Any good machine shop could do that.
  4. We’re always glade when things work out! The divider plate proximity to the impeller is another example of cavitation that creates flow disruptions. Way to go Frosty!
  5. Ok a couple things strike me. One depending on several things, taking the thermostat out can, not always, but can have a negative impact on engine temp! Pulley size, water pump design and radiator type/design can and does impact coolant flow! If the the combination allows free movement of the coolant it can circulate the coolant to fast never allowing it to stay in the radiator long enough to cool. If the combination causes a restriction in the right place it can cause cavitation, which can act as a type of air lock that causes heating problems. Sometimes it will even allow coolant to move through an engine in a non uniform manner causing localized heating because of areas that become stagnant in movement. Also you mention that you have a shroud and that the fan is 1” away from the radiator! I presume the shroud is deeper than 1”? If so and the shroud is a typical shroud that is built as a tapper, then the fan blade tips need to be placed at the smallest portion of the shroud opening. Otherwise the fan will actually cause cavitation of the air flow and become very in efficient at moving air through the radiator! To a degree it will act like blocking the front of the radiator to restrict air flow!
  6. Understandable, but just in case you’re not aware; you might want to either hang on to the 283 or sell it, even as is! To a good Hot Rodder they are gold! Any good muscle car guy worth his weight can take a two bolt main 283 and build one of the nastiest small block engine that ever existed. 600+ hp & 500 lb. of torque is an easy reach for that motor.
  7. Ahhh the memories! Dragway 42, Thompson drag raceway, Norwalk! I’ll never get to do that again, but remembering is always good! Thanks buddy! Now I have to go get a tissue!
  8. Yes, Pontiac, in those years did run a Chevy drivetrain. So the tranny should mate to any Chevy small block engine. That said, depending on what you have to spend and what kind of power you want? The 283 could be the better choice as a rebuild! If built right you could get anywhere from 400 to 500+ hp! Do you know what the tranny is?
  9. Copy that! It might fill up really quick! Had a little good weather! Got paint?
  10. Those are excellent jack stands! More than sufficient for even a 4000 lb car like my Lacrosse’s. The only thing I get concerned about with all of those types of jack stands are the top footprint. It’s conducive if there is a channel to place in the V groove of the top part of the jack or a good flat portion of frame, which today most cars don’t have! So I made my own many years age out of 3” pipe and pipe flanges! Very very stable & very strong! Still what you have is good!
  11. Good question Ringo! Depends on a number of factors. First are they tripods or four sided? Stamped steel or cast aluminum! Ratchet tooth or shear pin? If stamped steel do you know what gage or can you measure the thickness of the steel? Finally, do you use them to just change tires & oil or do you do more vigorous work under the car? Additionally I should include that each stand supports 3 ton. So say you have 4 stands & put the entire car in the air you are supporting, as an example, 2 ton with 12 ton! If we divide the car in quarters each quarter weighs approximately 1/2 a ton. Which is being supported by a 3 ton jack stand!
  12. Well, I’d say you got your money’s worth out of it! I figured you didn’t use Dex-cool, but you never know! That s- - t is bad stuff!
  13. I feel for you buddy! Been there do that, only in a stone driveway and no convertible! You are right, it's ugly! How old is the core? & Quick question, what kind of anti-freeze do you use?
  14. Welcome Thomas! I thought you were a Ford guy!
  15. Well when I built the valve covers for the 3800 on the Indian I had the right stock, but when I built the plenum cover I didn’t! So I made do with what I had. So now I will design and build a new arrangement! Not sure what it will look like yet, but it will be different. The valve covers have a deep fin, a more traditional look. the plenum cover is very shallow. Not the same kind of look!
