My 67 Belvedere has a 3.55 geared 8 3/4, with a tight 10 inch converter that only stalls about 2700. 1 3/4 headers with 2 1/2 inch exhaust out the back. Raced and driven on the same 255/60/15 MT Drag Radials.

The 440 features old school TRW flat tops on stock rods. The block and crank are stock, but feature studs in both the mains and heads. I use the modern ported stealth heads with the as supplied valve springs because it only has the old Comp magnum hyd. 270/470 cam. Since the cam is so small, I just re-used the stock rockers and pushrods (definitely helps with the budget). Cometic head gaskets, M-1 intake with 750 double pumper. 440 source 7 qt pan and pick-up with a melling HV pump. MP electronic distributor fired by an MSD digital 6.

The car will run 12.50s at 107-8 NA. I've done quite a bit of 11.50 index racing with it because I have a big shot plate on it( reason for the cometic gaskets). Best on the bottle is 11.31-122.5
