M-1 single plane intake on a 440 [ not a stroker ].

My current racer is a 1978 Dodge Challenger, with a 440. Engine is a stock forged crank, with Eagle rods and forged pistons, with a .509 hydraulic purple shaft. July 4th weekend it run 11.11, in the heat of the day and 119.6 mph. TM7 was in it when I got the car and I was lucky enough to get a new M1 from Indy CH, just last year. The carb I run is 750 Holley based, Nyutten 925 cfm, that I had built for another car 25 years ago. No other changes but the intake got me 1.5 mph.
