Is anyone running a SM420 with a big block? I'm in the process of swapping in a 75 C20 crossmember into my 65 C20. I was planning on using the 75 motor mount brackets and associated motor mounts, but that will locate the motor a couple inches too far forward.

Has anyone else done this?

Thanks for your help!
