I thought the motor mounts for small and big chevys were the same. I am doing the same swap into my swb 1/2 ton and never thought twice about the mounts, am I wrong?

SBC motor mounts will work. I am using them on mine. The fan shroud will be fine too. It will be a bolt in.

Captkaos-do you have headers on yours,according to the header manufacturer BB frame mounts are required,i dont see why it would matter but just want to be sure.

**Captkaos** · 12-31-2001, 02:49 PM

Yes I have headders on mine. Who is the manufacturer?

May I give a suggestion? They are high, but they will give you ground clearance. http://www.sandersonheaders.com 3/4 length Chevelle headers. I will be switching to these.
