Wonder of wonders, mackerel of mackerels*: the brand-new Dutra/Erson RV10-RDP cam I sent to Oregon Cam is back. They did a high-precision master measurement on it, and anyone can now have their solid-lifter Slant-6 cam reground into an RV10-RDP by requesting Grind № 2106R.


*-Not really wondrous or miraculous; I expected the cam to get there and back in perfect condition without any problems, and that's what happened.

AWESOME! Thanks for geting this done Dan!

Did you get a spec sheet for the cam?

Well done getting the cam mastered for future production....but it's a very slow rate cam for a Mopar lifter and seems to have long lash ramps. I think it would live a very long and happy life with a .904" lifter. I would question the merits of setting valve lash at .010" as listed on the card,that equates to about .007" lifter rise,add say .005" for push rod flex on those long rods and you will be opening valves at a pretty long duration for a mild cam. The figures listed for .010" LIFTER rise shows 291/317 duration,that appears to be still on the lash ramp, at .020" LIFTER rise it's showing 253/253 duration,a massive reduction and off the lash ramp.

So if you played it safe and kept off the lash ramps for valve opening you would need .020" lifter rise,less say .005" for rod flex so.015" lifter rise would be .022" lash at the valve. Anything less may work but it would be a very critical setting in order to keep it off the lash ramps in order to enjoy decent idle and performance,especially on a small cube engine with tight lsa ( yes I know slants like tighter lsa)

All I'm saying is be aware that you will likely need to play around with lash settings to obtain a decent outcome ,running cam card specs on lash won't equate to a happy engine in my opinion,nothing new about that,but I think it's even more critical on this grind.

Maybe Doc will chime in on the particulars of how this profile was arrived at.

It's a cam that works very well—better than the MP 244 cam, which itself is a nice upgrade from any of the stock cams, and better than the troublesome Comp 252 cam.

Comp cams usually run very aggressive ramps and pretty big lash numbers. The late and great Harold Brookshire was the cam God for many years and worked for several of the big companies,including Comp,but I think most of his lobes are now at Bullet Cams,they also have his ultra dyne masters as well,as for the comp stuff,Billy Godbold is there now,building cams for exhaust sound?? Eg the Thumpr series and the XE series are very aggressive and basically slam the valves shut... I have no first hand experience with the 252 profile,it may be old enough to be from their sensible era...but most modern performance Comp stuff is a joke as far as I'm concerned. I looked long an hard at their masters for a solid cam 351C, I just couldn't bring myself to running massive lashes they use since all the cams are specd for a 1.5 rocker,the 1.73 351C rocker made them look silly, Bullet came up with a sweet thing,thanks Harold!
Nothing wrong with a softer ramp,it's a mild cam after all,the owner would want a typically quiet and stable long lasting valve train... I just saw the lash numbers and thought I'd voice my concern,with a bit of lash tuning ( which is the usual case anyways) I'm sure it would run well,very well...obviously it has many times in the past!

TTBOMK it's a Chevrolet cam ground on a Mopar blank. Probably some people have managed to make it run OK, maybe even run well, but I've seen enough gross messes (can't make the engine run well and/or quietly no matter what lash is set to) to steer clear.

Yeah nice...at least they ground a small lobe on a bigger diameter cam,they have given a local cam company here a windfall by grinding LS lobes (large diameter cam) onto a much much much smaller V6 cam...it just don't work well let's say. In their defence that I know a very talented top end engine builder over here that uses a lot of Comp stuff and gets very impressive results,but we ain't talking catalogue cams or profiles any sane person would dream of using on the street,it seems they drop the ball on the milder stuff for some reason. That Slant intake lobe on the RDP may well be the old Erson RV lobe...nothing wrong with that,they had a good rep from what I've heard...and it's proven.

Bigger exhaust than intake? That is interesting.

May I ask why it is called an RDP? I was under the impression that stood for reverse dual pattern, which meant larger intake than exhaust? Please correct me if I am wrong...
