M-1 Intake Manifold

Follow the MP books modifications with air/fuel damns placed on the floor of the intake. These mods are to help balance out the intake when used with a Holley carb. Then there should be no problems.

Your overall combo should be considered and that includes the car and it’s weight.

The MP-M1 single plane was a basic copy with improvements over the Holley Strip Dominator. According to MP. So it will perform at least as well in the 3500-7000+ rpm range. It is more so a strip intake manifold than a street unit. If your concerned with around town low rpm driving, sell/trade the M1 for a RPM/LD340 or Stealth/Action Plus. These 4 intakes are excellent power makers that work awesome on the street.
My combination was on a 3100 lb swinger 4 speed 340 car I ran gear ratios from 355 to 430. I ran both an ld340 and a stealth manifolds prior to my m1. my car was 100% Street and the m1 was just Superior really didn't care about under 3000 RPM performance ,with the thermaquad combination it never seemed to be an issue. Throttle response on the m1 was beautiful in a whiplash kind of way!
