I'm funny, I like to answer the OP's question. I have done all the conversions and if I had a nice 318 sitting on a stand, I'd build the 318. Heck, I've had a 340 waiting in the wings for my 66 Barracuda for at least 30 years. Still running the 273. Never going to do all the changes to drop a 360 in for little gain.
