Anyone have opinions on the .474 version?

What exactly is the right combo for the .484? Most guys I've seen are running 3.91 gears. Will it work with 346 heads?

My only concern is the torque side. 71' Roadrunners weigh roughly 3800-4000lb so that's another factor.



I am running the Comp Cams Nostalgic Purple Plus .474 cam in my 383. Excelent low end and mid range. I agree on the gear though. No less than 3.55's. I switched from 3.91 to 3.73 and lost a little low end grunt, but she still lights up and moves nicely for a street motor. Dyno was 400/430 hp/tq. Build was 0.030 over, 516's with the 2.14/1.74 valves and some porting, Holley SD intake and a 650 mighty demon. Planning on an Eddy RPM to regain the bottom a bit in the future. Overall I am very happy with the combo.

This is just my opinion here though if you are going to go with an MP grind I would recommend going with the Nostalgia series from Comp. they use a more modern ramp profile and YES they ARE based on the .904 lifter. MP has had a tons of QC problems over the years. Here's a link to my cam card
