KRC Performance has a cam grind they call "RV". 200/206 480/480 lift on 112 with 1.6 RR. I have a set of Harland Sharp 1.7 RR on my stock 5.2L. What would happen if the 1.7 RR was used with this RV cam. Would it improve or hurt the performance of this cam.

Would it improve it? How about the idle, more lopey?

I don't beleive KRC has it listed on their web site. I found it while I was reading through the old posts. Bill, I think from KRC, had Comp Cams grind it and he put it in his Durango to try it out. With the pretty much stock (I don't remember all that was changed prior to this cam install, headers and R/T heads was) Durango, it made great torque and was very streetable.

I'm looking for a rebuild that I can run in our bi-annually mud race. The track (actually a trail) is about 1/8 mile long, with alot of mud/water pits, moguls,turns, and straight-a-ways. So alot of on/off the gas racing. Thought maybe this cam with the low rpm torque and higher rpm range would be a good fit.

Any other suggestions on a better cam? Thanks Ricker

I put the e-bay camin my watch page. The rust doesn't seem to bad, I think it would clean up. If I was going to sell a cam on e-bay I would at least make an attempt to try and clean it up, especially if the effort was taken of having it checked out by a local machine shop. Plus no cam card, not the end of the world for that price, I'll keep an eye on it. Thanks for the heads up. Alot of people have been pushing me toward the KRC 206x 206/210dur. 480/512lift 108. A friend said this cam should do everything I want plus have the lopey idle I was looking for. I'll keep ya posted on decision. Thanks again Ricker

A little update...I ended up calling Comp Cams and with the motor I'm building they suggested thier #20-746-9 cam. I believe this is the same cam that Harsh-R/T is using.
265/273 Duration (216/224 @ .050)
506/ 506 Lift 114 LSA

I want to use this with 1.7 RR, so I can get more lift (Mopar 6062 .600" lift springs will also be used). What would be my lift with these? I'm thinking .538"

I'm sorry, when I first started this thread back in Feb. I was looking to rebuild the 5.2L that was in the truck, but after tearing it down I found some problems and a friend had a 5.9L block that was already machined for a stroker build, so I changed horses in mid stream and went with a 408. I didn't realize I never updated this thread until now.
The Ross pistons I'm using have the valve cuts in them.
