I am rebuilding or frame off restoration(first one) on a 1965 Grand Prix.  The old 389 engine is tight, and I want to put a 455HO in it.  Are there any conversion kits available for the engine mounts. I have been looking everywhere on the net but no luck... It gets tireing looking for stuff on the net.

Anyone have any info??
Thanks

i just put a 72 455 in my 66 bonneville and used stock 66 389 motor mounts. my 455 has 4 bolt holes on each side of the block to bolt up the mounts (two different positions). take the mounts off the 389 and see if they will go in the same spot on the 455. i got brand new mounts at the local parts store.
