Since this thread is off the rails anyhow...
In 1994 I helped a good friend build a low$$ 360, stock stroke, speed pro h405p pistons .060, MP 284/484cam, 850 DP, generic a body headers, 904 with 4000 stall GER(, yeah, a GER) converter. He had a Streetmaster intake and I told him to get a real one. The Dart went 8.5s in the 1/8th. Mid summer he picked up a single plane M1. That change dropped it to 8.10 in the 1/8th. No other changes. By the end of the summer it ran 7.8s.
I was young and had a lot to learn, still do. I just feel that the 360 needed more than what the Streetmaster could give it.
That is my real world experience.
Form your own opinions.
Maybe we were too dumb to extract the power from the Streetmaster..
Maybe the 360 needed more flow, that the M1 provided.
Whatever you think, it is fine , if you think I'm dumb, it won't bother me.
Edit: Maybe the power of the S-master was blowing through the GER converter, hence the slower times... Maybe I need to rethink this....
