That's a HUGE gain for an intake swap! Was it 100% intake to intake?

Poor Victor casting?
Mods to M1...porting?
Any fuel curve changes...jetting, PV's??
Same track and weather conditions as your previous best?
Launch and shift RPM the same???

Thanks!

Intake swap only. Both intakes gasket matched and are nice castings. I used moroso ab epoxy on the M1 carb flange to convert it from spreadbore to square flange. Hotter temp and poor track prep for the runs with the M1. Launch at 4500 rpm, shifting at 6600 rpm for both intakes. The M1 will easily out 60' the victor in my application and has the same top end. My overall 1/4 mile ET average with the victor was 11.8, average with the M1 is 11.5. Victor plenum is probably to large and runner length is too short for the RPM range I'm running.
