Okay,,,I've had my chain jerked before,,, but not like this. You mean to tell me you "don't know" what that thing in your floor is? As expensive as that thing should be, I would know exactly what it was, who assembled it, what lift, duration, ratio, rod length,etc., etc.
And I'm no expert (i once mistook a 1916 Buick engine for a 1919 Haynes-Apperson), but come on,,,,,,that thing is big block Chevy. With that odd-ball intake on there, I can't tell who's heads those are, and with that motor plate, I can't tell who's block that is. But if its a GMPP Bow-tie, Merlin, World, Dart, EPW, Wal-Mart, etc. It should not matter. It's a big block Chevy or a replacement of. That's it's intent.
The intent of the 'motor swap' rule, is for you to install a Packard, Studebaker, or Hudson engine in your Camaro.
So next time you post, I'd like to see a complete spec sheet, including wrist pin length, wall thickness,and weight(these are the things I would know if that were my engine)
And what about number 4= lots of pictures.
Waiting for the pics, RICK
