Re: ZL-1 motor build
Hey Al!
Fantastic!  Keep the images and posts coming. I for one will be following this very closely. Of particular interest to me will be the internals to this build and how well it runs. What are your plane for octane level, compression, etc..... Nuch

Re: ZL-1 motor build
Al,
This is always an interesting BBC subject. I believe the reason that the '7115 crankshaft was used in the L-88 and ZL-1 applications was due mainly to the towering dome heights of the pistons and the reciprocating forces that ensued. I've never gotten a definitive answer on that issue. Anyway know? Nuch

Shouldn't this kind of post be banned under our "no political threads" rule???
