Look at this: This is a CUCV frame I just stripped, so I can frame swap from the twisted frame. Everything is on a 1/2 / 3/4 ton frame ('73 K20), going onto a 1 ton frame. This question is about the crossmember that the red arrow points to.... Since this was a 6.2, will I have any interference issues with that when I put in a smallblock? Second question if for the motor mounts....these will work with a 350, right? Also, it's probably a good idea to put in new mounts (at the very least, the rubber). Where can I get (inexpensive) new motor mounts (or rubber)??? Same question/concern for the tranny crossmember.... The rubber mounts that go between the crossmember and the 'case - where can I get those, good and cheap??
