I have a 70 Camaro with a totally stock 350 boasting 250 hp, yawn, I am going to swap the heads with a set of 69 camel hump heads from a 69 z 28 that have been ported and polished hardened valve seats the valves are 202/165 with double springs(red) set up for solid lifters. The intake will be a dual plane airgap
Topped off with a 600 cfm edelbrock carb.
The question is what cam should I be looking at? Don't care about mileage. If I have to change stahl convert or I can do that as I have a 400 with a high stahl waiting in the wings. I'd rather not if I don't have to but I can.

 

Headers, gears and to be honest you'd be much better off with a cheap set of aftermarket aluminum heads to help carry off the combustion chamber heat. Ditch the edelbrock for a 750 holley. If you are going solid lifter you must want to run up to 7000 and those cast pistons will be your downfall if you dont run it really rich.
A bone stock 70 is going to have 3.08's or 3/31's at best. If its not a daily driver and you dont care about mileage ditch the highway gears and go with 3.73's or 4.11's.

With the right gearing and a decent carb and a 2500 or so stall ( The TH350 is fine with a shift kit ) and somewhere int he range of a comp cams 294S Magnum cam will have a aggressive idle and it will wind right up there.
