all my american cars hafe bin auto (trans am,camaro corvette other stang)

thanks, �*var iceland

 

well, i cant answer the question about how much nitrous, but i can answer some of the others and give some pointer.

as long as the bellhousing fits a small block ford, it will fit the 351W. you can use the heads from the 302 on the 351W. you will just have to drill out the head bolt holes to 1/2". the stock pistons probably cant take much, i bet if you asked the company you want to purchase from they could help u out. and if u have any others q's on the 351W i can help u out.
