Re: J-Grind Cam
I looked through a few things I have.. I think the "J" grind might have been the .625-626 lift cam. I have an article on a wildass '68 Motion SS427 L88 Chevelle and it saids it had the "J" cam but didn't list any specs. The "C" grind was .610 lift and is in the Ko-Motion Vette. Thats all I found but I only looked quick.
