While at H-O Racing in the 1970s I made thousands of Pontiac-specific cam recommendations and sold a like number to satisfied customers.

The fact that this is going into a 2200lb Tempest does make a big difference. What you essentially have is a 1963 Tempest 421SD. I've personally owned two 1963 Tempests, one with a 428 and one with a Ram Air III 400. Also, I personally know Jim Christensen who owned the ex-Mickey Thompson #749 A/FX Factory 421 Tempest drag car. I know from where I speak.

Given the additional information, the Summit 2802/744 is not enough cam for your combination. Pontiac used the McKellar #10 mechanical flat tappet cam (essentially a Ram Air IV) in all of their 1963 A/FX cars. Summit does not make a hydraulic flat tappet with enough duration for what you have. Therefore the 2802 will seem mild in your setup.

But, it's your car and your $. Do what you want. I have nothing further to say on the subject because I told you what I think and I don't sell cams anymore.
