My MP 557 cam is very smooth even right off idle so if I can cruise down the highway at less than 2500 RPM's I'll be all set.


Mine runs 2900ish at 75 MPH. 3.23's with 28" tall 275/60/15 tires.

What stall is your converter? I'd change the gears first and see how the converter likes it before I would change it.

It's a 9.5" Dynamic, I haven't tested the flash on it as I haven't even had any sticky tires on the car yet, it's probably around 4000-4400 with my 500" motor. I'm gonna try the gears but I really think the 3.23's will make the converter slip more.
