Big Block swap

[drag_77]

Question on big block motor mounts(frame side). When you are going from a small block to big block in a 72 Nova is it best to use the correct frame mounts or will the small block mounts work?

I just went from a SB to BB and I used the original SB Frame Mounts and everything fit nicely on our 70' Nova. Do you have a Power Brake Booster? If so I think that might be the only issue.

I removed the brake booster they usually interfer when you use the tall valve covers. Would you happen to have the part number off of the mounts. I have two different sets.

I also use SB frame mounts.
