The standard-port M1 fit w/ the MW ports? Are the Trick Flow MW ports smaller than "normal" MW ports, by some chance?
Yes, the M1 manifold fit on the 270 heads. There wasn't a lot of extra material around the ports so I'm not so sure I'd try it on a daily driver but it worked fine on the dyno. Here is a link to the magazine article: http://www.hotrod.com/articles/dyno-day-trick-flow-270-mopar-heads/
You have to kind of piece the information together since it wasn't what I was trying to showcase in the article. But I didn't hide the fact either that the Indy intake wasn't very good so we swapped the Wilson ported M1 back on the engine. The engine ran great with the Wilson ported M1 on the 270 heads. It ran better than I thought it would since the standard port intake dumping into MW port heads has a really big step.
