3.1 V6 to a 350 swap
I am getting rid of the stock 3.1 v6 for a 350 block. My quick question to all the motor gods in here is this.... will it fit the stock motor mounts or will I have to modify my mounts? It is a 1991 firebird stock.

Re: 3.1 V6 to a 350 swap
Don't know if the mounts are different - a check of part numbers at autozone.com would tell you. I do know they need to move forward as the V8 is longer, but there are mount holes already in the subframe.
Try
- there's a ton of threads and stickies on V6 to V8 swaps.

The info is in the V6 to V8 swap sticky in the top section of this forum.
