just because you can, don't necessarily mean you should

while i'm having to replace my engine mow, i could take another 4.3 & turn it into a 302 using a .060 overbore & 4.00" stroke. the block would most likely take a dump shortly afterwards! that's why i'm trying to work out a 5.3 swap (and any help on finding a complete motor w/ harness would really help!)
