Who is doing the engine?
I have and will give a complete FE ( 360 ) to a machine shop.
It is almost complete. But for all intensive purposes, it could easily be punched to 406 - 428 slugs. The heads are truck smog style, but I can toss in a set of 6040s.
Here is the problem, Either it is going to have to be some place close to Detroit, OR there is going to have to be an effort to get it shipped.
