I bet that this has been covered before, but I'm not sure how to do a search. At any rate, I now have a 54 Chevrolet 3100. None of the drive train is stock. It presently has a straight 6, and I want to replace that with a small block, Chevy 350, 4 bolt main. Are there any simple, "bolt on" kits available as far as motor mounts? If not, what do I have to do, and does it involve major modifications? Any advice on how to best and most easily accomplish this will be appreciated.

Also, mechanics tell me that the present Chevrolet 3 speed standard transmission (linkage is 3 on the tree) will bolt right up to the engine---but i may eventually want to swap out an automatic in the near future. Any special provisions that I need to do now for that possible eventuality? wjb
