Hey everyone! I recently purchased a 1971 ford Torino sedan that is in mint condition (interior looks new from factory and zero rust). It currently has a 302, c4, and 8 inch rear end in it. I would like to get more horsepower and performance out of it but since the car is in such good condition I don't really want to permanently modify it. I've been looking into swapping a 429 or 460 into it or maybe a 351 Cleveland but am unsure how much modification is required for these kinds of swaps. I know for the big blocks they need different engine mounts and the drive shaft shortened which is fine but will they fit in the trans tunnel? Any advice is much appreciated.
