MY SITUATION: I recently bought a 1966 Cutlass Covertible for a driver, not a show car; I can't sit still long enough for shows. This 66 cutlass came to me with a mid 70's (1974 I think) 403 motor installed that runs quite nicely. It seems well suited to the transmission, is pretty easy on gas, starts every time, and happily burns today's junk gas without complaint. MY PROBLEM: I do notice that the motor torques up when I accelerate quickly, so I am going to assume I have a motor mount problem. MY STUPID QUESTION IS: Assuming the mounts weren't properly installed by the previous owner, should my primary concern be finding motor mounts that are a perfect fit for the engine or a perfect fit for the frame? Or by some quirk of fate might I actually expect to find mounts that will work without alteration or welding? I figure asking here is the wisest course of action since I usually get pretty good advice. Obviously I'm a green horn learning as I go, so any and all advice is appreciated.
