It has a .506 lift with a 1.5 rocker. Recalculate it with the Magnum heads rocker of 1.6 which equals .539 (-733333333)
Rhodes lists a reduction of .010 - .020. (.529 - .519)
& a cut in duration of 10 - 15 degrees @050 that is restored @ approximately 3500 rpm. They claim an increase of 1-2 inches of vacuum.

So this is why and Dmopower are looking at these lifters. Today, you can call it what Dmopower said, a poor man’s VVT. I’ve done this in the past, used these lifters in this thought process. Just not with ported heads looking for mileage. But his thoughts, IMO, have merit. Now he’ll find out if it works for him.

Normally I had much larger cams and power brakes to contend with, so, these lifters got the nod.

Rhoades also has other lifters that are able to reduce the duration @050 a little bit more and there are other features you can get with them as well.

Check’em out!
