The forums name is for A bodies. The forum this thread is in is "Small Block Mopar Engine" which is what we are talking about. If you don't like the 318 discussion here you are free to check out a 340 thread.
All he likes to do is troll, start 318 strawman arguments and if there's no active 318 thread he'll dig some up lol, then play victim when people argue back.
As for being /6,273,318 forum, my guess 80-90% of A Bodies came with these engines.
