AGTO8U,
I see you're located in OK, was wondering where?
You will certainly see a difference. I did essentially the same thing on a '72 350, but used 1970 small valve #16 heads that were shaved to 68cc. Same cam spec, used performer intake and edelbrock carb (which hasn't been tuned). Flowing thru stock log manifolds into 2" duals.
Stock 2 bbl single exhaust 72 350 was factory rated 150 bhp at the flywheel with full accessories. Last dyno session mine put 247 hp and 308 tq to the wheels.
I plan to run ram air exhaust and tune the carb next. Then possibly going bigger with the cam.
Hope some of this is helpful.
