Some M1 porting pictures and flow numbers

Not too darn shabby at all. I agree with and on what the intake was designed for. When they made it, there were no Edelbrock heads available. Not many people have ported the head as far as you found it can go. Many places would call 280/290 right close to its maximum when the head first came out and for a while.

Considering it was made for a stock cast iron head and how far the can go ported, I’d say that is a very good intake for an OE head and really good for it now.

Everybody give John a round of applause for his first ever MoPar M1 single plane work.

Thanks John!
