Good Lord, James. I used to think the motor in my Lister was hot stuff until people like you and Gary Sharapata came along. Maybe you can use my little small block Chevy as a starter motor for that thing.
I think you need to keep the injection stacks--why be subtle? In fact, why don't you get a set of those staggered injectors like they ran on the Can Am cars...now THAT would be cool.
