Don't underestimate a well thought out small block. Read this thread about my 68 cuda.

Might take a while but there is a ton of good info in there, not just by me either. A few highlights are a best of 29 mpg on 93 octane and 27 on e-85, both times running 65 mph.

I am close enought to haveing my 416 parts together I would just sell the entire engine and trans out of it but oregan is a ways away.

I am not causing global warming, I am just trying to hold off a impending Ice Age!
