How much power for 350

I don't really know what kind of heads you have but assuming stock heads, I would have to say 275-300 horse.

It's impossible to give a close estimate. You need to find a dyno and have it tested.

300hp seems reasonable.

here is a site will over 100 sbc combos dyno'd. Kind of a strange pairing being a sbc dyno and bible website.

The site shows that stock heads suck. You really need some good aftermarket heads to make hp. You should be making 350 hp with a 350 and a mild cam.
