Damn how much hp? And yeah the rpm ran better on the street imo and at the strip. I did run a one inch carb spacer on it. It had x heads had a little clean up on the port noting serious. But anyway it ran a tenth or two better the m1 intake has its advantages it ran better at 6-6500 I dident dyno or anthing but if I had a solid cam I’d run the m1.
