Re: Estimated horsepower?
200 net if youre lucky.
A lot depends on that cam, a big lopey cam will hurt more than help on that combo.

Re: Estimated horsepower?
Thanks,kinda what I was thinking.Down the road the 290hp 350ci crate would be a very noticeable upgrade.

Re: Estimated horsepower?
That's interesting: I had a 307 '71 SWB when I was 17. Did pretty much exactly the same mods to my engine as was done to yours: Corvette intake, 600 Holley, headers with glass packs and a mild cam. No matter what I did to it though, it never seemed to get any faster - it just got louder.
