Chevy man needs a Mopar lesson

To help answer the question in a different way;

The 318 was the basic transportation engine above the slant six. (/6)
It was notoofered with a 4bbl until late in it's life, the late 70's. It still wasn't a performer due to emmisions strappings.

You can equal the 318 to the same basic transportation engine as Ford 302 and Chevys 305/307/327 etc.....

The 360 was the same deal only larger. Used as a basic transport engine, it's debut was a 2bbl. but it 74 it did come with a 4bbl. Not a stela performer with emmisions on top or high compresion, but not bad.

You can equal this engine to the Frod 351 or Chevy 350 in non-performance terms. Just a bigger passenger car mover.
