If you're going to tear it down and go with heads and a cam, you might as well go with a 350 or larger. Unless you can't for some reason.

Re: how do i get 300HP

Ultimate tbi mods, ZZ4 heads and cam, a matching intake and a tune should have it pretty easily.

Re: how do i get 300HP

That depends on what cam you put in. The stock one will be around 1600 RPM or so with a modded motor. Maybe 2000-2400, depending on the cam.

Re: how do i get 300HP

Well what size cam and stall converter will make for a much more powerful take off at a reasonable price?
