1969 Camaro BBC to SBC frame stands
 

Would the big block frame stands work even though they are lower with my Moroso solid engine mounts when putting a small block in or should I just put the small block mounts in? If i get the SBC mounts which ones are correct? I've seen a few different part #s.

I'd consider removing the stands, and replacing them, for no other reason than to sell your original bbc stands. You should be able to get replacement stands really cheap, or maybe trade with someone going sbc to bbc.

This will help you out on the different type of stands. http://www.pozziracing.com/camaro_engine.htm
I have a new pair you can have for cheap. I sent a PM.
