I have a friend at school that is thinking about getting rid of the 4.3 in his '05 chevy 4.3 v6 5 speed, I'm thinking this may be a fairly simple swap, just change the harness and computer and drop in the engine with v8 specific parts. We located a complete 5.3, computer and harness for $750. I think he is going to need the following:
Fan
throttle cable
engine mounts
flywheel
air intake pluming
modified exhaust

Anything else you guys can think of? Will it work to swap the harness?
