I forgot to mention in my post about the RPM vs the M1 and the car in question was running faster than yours.
Ink self would never use a single plane on a stock stroke engine unless it was in the 10’s. Also, not to be a jerk about it, but you didn’t have enough engine under the M1 and your comparison is an I’ll one with the amount of changes done.
A 750 to 950, 246@050 to a 260@050, stock Edelbrock heads to minor ported heads. Seriously, this is two different engines.
