So this is what I am starting with. My good friend Tom K has a 62 BelAir 2 door post with what we think is a 409 with mismatched cylinder heads and a turbo 350 tranny. So let the games begin. Got the heads off and surprised to find a standard bore 409 pass block with H/P pistons. Lifters and cam look good its a solid but not sure what it is but we are just going to stay with for better or worst. The block is a 65 block so last of the 409 run hope we don't break it. Now we have a fresh set of 690 heads to install on it and get it dialed in with the 2X4 factory intake and a pair of AFB carbs. Next we will start on the chassis buy installing some adjustable shocks all the way around remove P/S and install a spool with some 4.88. Then we will install a billet center support bearing holder on the drive shaft the change wheels a tires so it will hook up. I will try and up date as I get further along.
