**ScottH** · 05-23-2013, 11:32 PM

Will be getting a 83 swb in the near future that was originally a 250 6 cyl engine.
I plan to put a sbc in and was wondering what is needed to make the change?
Can I use the engine mounts from the 6? Do they need to be relocated?
I am thinking about using the original sm465 trans & would like to keep in the 6 position (trans, cross member, etc.).

Any info is appreciated.

Thanks guys!
Scott
