300 mount solution?
Posted by: Wilitrun

Hi all,
I'm wondering if anyone is marketing a conversion mount for the 300 swap as it's starting to become more common.
Specifically I'd be primarily interested in one that mounts to the side of the block and straddles the frame rail vertically rather than using the stock frame ears. It seems the 300 is wide enough that the clearances I'm seeing on the 215 swaps just don't translate to what my block is telling me mocked up in the car and I want to give myself as much lateral room as possible.
Alternately, if someone has a pattern that's worked for them I can make something but I haven't finished gathering all my parts and so the final position of the engine is not yet known. Cheers.
