What do you guys think of the Comp Cams Pro-Magnum 1.85 Rocker arm set? I am considering changing the intake to a FAST, and going with these rockers. Along with my other mods, Headers, CAI, and Tune, it should put me real close to 400 rwhp which has been my goal. The car is advertised to have 400 hp I just want it to the rear wheels. I think this is where I will stop the engine mods. But looking for opinions. Thanks

With the Pro Magnum Rockers you get the best of both worlds. Pro Magnum Rockers are made of 8650 chromemoly steel. This material is some three times stronger than 7075-T6 aluminum which is used for most aluminum rocker arms. Our engineers used advanced computer technology (including Finite Element Analysis) to refine the Pro Magnum Rocker. We added strength where it was needed and reduced mass in low stress areas. The result: Pro Magnum Rocker Arms have less weight (5%) at the valve than most aluminum rockers. This means more RPM and valve train stability.

I think with a FAST, you might go over the 400rwhp mark with a good tune. I've got long-tubes, cat-back, VR, SLP 1.85 rockers and a ported intake with a best of 397rwhp/387rwtq SAE. My ported intake didn't give much in the peak department but good gains in the mid-range. Another fellow has the same mods but I think the rockers you've got, the FAST and made 407rwhp and about the same in torque.

Any thing around 400 will be fine and if it goes over that is just icing on the cake.

You might have clearance issues with the Pro Magnums, not sure though. I was going to do the same thing except I am going with a stock ported intake and TB. My shop recommended that I would be better off going with a cam as the power gain is better and the labor cost is not much more than installing rockers. They also have had/seen some non-adjustable ones come loose and that's not good, these were not installation issues either, just the nature of some rockers. Needless to say I am doing a milder cam as I don't need a dropped valve or some other catastraphic episode happening b/c of a loose rocker, but this is just my opinion based on information from people much more knowledgeable about this than I am. Also, my car is a DD. Just do your research and talk to the people at a shop you can trust and make an informed decision and you'll be okay. :thumbsup:

Thanks for the information, I do plan on talking to them about both options. That being the Rockers or a small Cam.

Did you end up going with the Comp Cam's Pro Mag roller rocker kit? I'm also thinking of getting that kit installed with my FAST intake manifold. Where were you thinking of buying this kit and have you read any reviews on hp gains with this kit?

I did finally make a decision. Yes, I am going with the Pro-Magnums, and the FAST. They will be ordered today from my tuner, and installed in a week or so. I will let you know the results when the job is complete.
