That ZL-1 is beautiful. Putting it on the rug was a nice touch.

Re: ZL-1 motor build
I don't know if you've purchased your solid roller camshaft yet, but if you havent, you should really consider the Comp Cams 288 Street Roller. It's a great camshaft that I (and many others) have used with great success. Easy on the valvetrain and great power. I put many reliable miles and 1/4 mile passes on mine with never a problem. Very popular and with good reason.

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
