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
