Hey guys, I'm going to swap out my stock '75 454 that came in my '57 suburban 4x4. I'm going to put in a friend of mine built crate 350 that he no longer needs. My 454 has issues and I feel that I would be much farther ahead to swap out than put the time and money into the motor that I have no history of and looks to have been somewhat mis-cared for in the past. The 350 has approximately 10k miles on it and has been in dry storage for about 6 yrs. What I need to know is, will I need to swap out the motor mounts? I was told by my buddy that they make adapter motor mounts that go from a sbc to a bbc and vise versa, is this true? Where would I find these? Has anyone done this? any other things I need to know or plan for?Any advice would help. Thanks, Bongo
