Any cam in the low 220's on duration and low 500's on lift. I would be willing to bet money that a stock 5.0 cam and 1.7 rockers would be very close to any cam below 5800 rpm in hp. Since it is a stick car I would keep it as small as I thaught I could. Bigger than stock cams always seem to make a stick car lazy will driving stop light to stop light in traffic. Just my opinion I am no expert.
F cam is good for 302. If you have not done the 347 yet ..... DONT.
Just rebuild it has a 302 with an F cam and some good heads.
You will easily break the block with that combo. Hit 500rwhp at 12psi or so.
