'67 Camaro E/SA redo

Rich, the frame mounts are also different between small blocks and big blocks. It's easy to end up with a mismatch of motor mounts and frame mounts. And from side to side as things have been swapped around over the years. Generally, the dead give away is if theres a 1/4" spacer or stack of washers between the engine mount and the frame mount to compensate for the motor mount width...but not always. I've seen aftermarket solid mounts that are combinations of both dimensions. Here's some dimensions to help identify what frame mounts you have:

Small block:
Driver's side: 2- 9/16" tall
Pass side is 2- 3/4" tall.

Big block:
Drivers side: 2- 7/8" tall
Pass Side: 2- 1/2" tall

Basically, small blocks use the 'short/wide' setup and big blocks use the 'tall/narrow' setup. The '67-'69 Z-28's supposedly use the big block style (tall/narrow) setup....whew.

Just my understanding of it...... -Al
