i currently have a edelbrock performer rpm intake and want the cam and lifters to match how does this perform who else has used it im looking for some good power gains but still would like to have a decent amount of driveability sence its my only mode of transpertation would i be better off with a 'custom cam??' sence its my only mode of transpertation ?/?

This cam is an old design and you can do much better. You don't give many clues as to what your engine is so a recommendation is a little hard. Ring Comp Cams or Crane (or your fave cam manufacturer) for some advice.

Hey Cosmik, if you decide to go with this cam shoot me an e-mail. I have seen these in several 350's and they run pretty good. They are a little older in design but the cam will still let the engine pull hard (provided your set up is right). They have a decent lope to them but are still very streetable with good vacuum. If you build the engine to Edelbrocks specs, you can get ~420 hp (thats with the RPM heads too of course) I can get you one real cheap if you still want one! I started my engine project planning on putting one in with an RPM AirGap manifold. I later changed my mind and went with a CompCams solid roller cam. I just figured I wanted a roller instead of a flat tappet cam. Anyways, I still have the RPM cam, in the box, with the high-rev/fast bleed type lifters, lube and literature. I got it, looked at it, and shelved until I got the rest of the engine parts. Send me an e-mail and I'll make you a good deal. Just to check its the #7102 cam kit.

The Performer RPM cam will work well if:
matched up with the right other components
Should have 9.5 or more compression ratio
some good breathing heads like edelbrock performer rpm or vortecs or anything as good or better.
The performer RPM intake
A good set of headers and hi flow exhaust.
This cam will start to work (torque curve) around 3000rpm
so a 3500+ rpm converter would be best.
Should use a high rear gear ratio like 3.73 or 4.10 for the street
and track. Unless you plan on running Bonneville.
You'll need some good performance stock diameter valve springs
like the Edelbrock RPM/ torker plus springs.
There is nothing old about this cam grind.
This cam will have reduced manifold vacuum at idle and may require a carb power valve/power spring replacement.
This cam is right on the borderline and may or may not affect
your powerbrakes. The high bleed down lifters will help in this area. If you want strong power from 3000 to 6000+, this is a good one. If you want economical cruiseing on the hwy, pick a smaller one.

I had this cam in my 68 Camaro. It has an awesome lope at idle. You would get many many compliments from the sound at idle, but it does not have much at low RPM. It really doesnt wake up until 2800-3000 so you would have to compensate for that awith a loose converter, but other than that it was a great cam!!

F-Bird'88 is dead on. I have run this cam and was very pleased.

I wasn't the one who was going to use the cam. If it were my car and the engine was a 350 I would probably go with a Comp cams 268. The original poster didn't say what engine he had. It could be a 305 in which case the Performer RPM cam is far too big.

All IMHO of course

oopS! Didn't scroll far enough up! Sorry Cosmik! I ended up going with the CompCams 280 solid roller for my 383ci.
Speedfreaker..........e-mail me if you decide to go with the RPM cam.

I have the Edelbrock performer RPM cam,carb,intake,.a 2400-3000 stall converter.3.70 gears.And 10..5 compression with a set of pocket ported and bowl blended 931 heads.Haven't been to the track ,but it seems to pull hard and really comes alive on the top end.Any one have an estimates on Hp and torque or quarter mile times.

Brandog87GTA

Well I run the same cam, and with my 84 MPH in the 1/8 I should run high 12's in the quarter with slicks. Keep in mind my motor is limited by the 3.27 gear. I love the cam, it pull extremely well and I have turned 6500 and it doesnt fall off. I think its key to power is in its duration.

Cosmik Debris

This is all well and good but the original poster said he had an intake and wanted a cam to match. No head work and he wanted it streetable. He doesn't say whether he has the original 305 or a 350 in his car. If he has a 305 that cam is way too big! With only an intake and no head work that cam is not even going to be any good in a 350. That cam may be fine in certain engines (although I still think you can do better) but not in the original poster's car.

um ok youg uys i guess i have to be a little more specific on my motor and mods well i have the 305 motor with the quadrajet an edelbrock performer rpm intake a 160 thermostat and have all the smog taken off also i just got the transmission {700r4} rebuilt with a shift kit and am gitting a new exhaust setup everything else is stock to my knowledge hopefully this will help if this cam is not going to help me any what would you guys recamend would the edelbrock performer cam work well???

Cosmik Debris

The performer cam is not much better than the cam you have already. If you have the L69 motor then the performer cam is about the same. A good cam for a fairly stock 305 is the Comp Cams XE256. You may even want to go to an XE262. This will push the power band to the high 5000s. You may not get away with a stock converter with this cam however.

All IMHO of course.

speedfreaker

i really want to keep my stock converter so whats the max thanks

Sitting Bull

Then the Comp Cams XE256 is as high as you want to go. That is straight from the tech folks at Comp Cams, too

Dragula

Definitely can't keep the stock converter with the RPM cam

WickedBowtie

Old thread but have a question on the lifters for this cam. I'm getting mixed stories on priming the lifters and preload on these specific lifters. Any input?
