I am considering the RPM Performer package for my 350, but want to make sure this package will work with my block. I have a 350 runnng 9.5 to 1 compression. The block as less than 2k miles on it snce it was built in 1998. It is a 1970 2 bolt main block and I was worried about getting 6500 RPM out of it. It is advertised at 410 hp and was wondering if my block would handle this package. I am also converting to a built 200r4 tranny with a 3k stall converter and the tranny has a WOT Shift of 6K. My current set up has a max RPM of 5k. This set up appears to be good bang for the buck, but I wanted to throw this out there. It comes wth Heads, Cam, Intake

I had the RPM package on a 383 in my Chevelle. When I pulled the engine after 2500 miles to paint the car, I pulled the pan just to check the bearings and glad I did!!!! I had severe cap walk with my two bolt block. I was lucky enough to find a fresh machined 010 4-bolt main at a swap meet for $250.00 and rebuilt it into that block.

I would do some research before your purchase. I think the manifold is great, heads are decent and the cam not so good. I bought my RPM heads for a 327, ended up building a 388, I wished I would have reseached the heads a little more, because of the larger engine. Don't get me wrong the heads are one of the best for under $1,000. A magazine compaired a bunch of heads for under $1,000 and the RPM were on top with TFS. Lots of people are going to steer you away from the cam. It's an old school grind, there is much better cams out there now for the same price.

The cam is very dated. There are better options Lunati VooDoo cams were designed by Harold (Ultradyne) who frequents Chevelles.com
The manifold is very good, the heads decent, especially for the money.
What heads do you have now?
What rear gears are you pulling now? (This will play into cam selection)

I am running stock style heads which I believe are 64CC
I plan on running 3:55 in the rear. I found some performer heads locally for $500 but was really interested in the RPM package. There was no specs on whether it required a 2 bolt or 4 bolt main block.
I basicly hav an RV/towing cam now that is simular to a stock style corvette cam of 1969 (per the builder)

Some of those packages consist of a carb , intake, assembled heads, cam and lifters, maybe a timing chain set up. Very stock kits. As mentioned, the cams are very mild generics. Mostly directed for public that is not too in the know about stuff. They will fit most any sbc , dont take in account the type of block .

Please consider Holley's SB 20 degree heads here as well as a Lunati or UDHarold cam!!

I agree with everything said! Great manifolds, good heads......and the rest leaves a nice amount to be desired.

Youd be just fine with one of their manifolds.....and I wouldnt mind the heads either, but lemme give you a quick run down of a build that Id build.

First of all....verify your pistons to be SURE that your going to end up with somewhere around 9.5 or 10:1 comp. That way you know what chamber size you need out of a head to keep compression reasoable without going waay to low or high.

Next in line....look at the brodix iron killer aluminum heads with the CNC chamber option. Best heads for the money. They might cost a couple dollars more than the eddy heads....but in my opinion they are better than anything else in their price range without stepping up to the 1400 hundred dollar plus stuff. The 180CC heads will be great.....the 200 CC deals are a little large but not too big especially if you want room to grow.

For the intake....edelbrock performer rpm.

Cam.....lunati voodoo 268

Carb... a good holley 650-750.

Some 1 3/4 headers and good ignition(nothing fancy) and your good to go.

This is a much more modernized combo. It would be a stretch to expect more than 420 horsepower out of this combo on an HONEST dyno......but average power is where its at. The power and response over the ENTIRE power curve will be better than with the older(but good) heads and definitely dated edelbrock cam!

Thats what will make it shine over the edelbrock package. Its not going to be a super high horsepower build....but it will be enough and it will drive nicer(nicer response and street manners) and have more power all over the place.

Although this is the way I would prefer to do things....I wouldnt be opposed to using the entire performer rpm power package with the exception of a modern cam. It will still run darn well for a street motor.

I dont like the cam though unless its in a nitrous motor! We have had good luck with those cam specs(or the generic summit copy of that cam) in budget nitrous build small blocks. Its just not as "peppy" on all motor as the new stuff.

I was in the same situation about 1 1/2 years ago. I was going to buy the package to hold down costs and simplfy selection. I ended up with the RPM heads, RPM intake, Voodoo 268 cam & lifters and roller-tip rockers. I used slightly longer push rods per Edelbrocks recommendation). On my 355, comp is now about 10:1 and the thing screams.
I'm running a 4-speed and 4:11 gears. I don't have experience with the Edelbrock cam, but I think you could make a better cam selection and make more power with another grind.

Great info, I liked the specs on the voodoo 268 Cam. I have a Carter afb 650 carb that I plan on using. Will my 2 bolt main block be able to spin at 6200 to 6500 rpms. I don't believe it is balanced.
Lastly what is the diference from Edelbrock performer heads vs Edelbrock RPM heads. Would the performer heads do the same job as the rpms as the specs look simular

Personally I don't think a 2 bolt main will handle those RPM's for very long making that kind of HP. I wouldn't do it.

Ken,

I went with the Eldy E-Tec 200 heads and RPM Air Gap intake on my 383 stroker and IMO it is a great combo for the street. Great flow on these heads. I have to agree with the other posts about the cam. Look into Comp Cams. Granted I am using a 4 bolt main and new rotating assembly but with 10.5:1 compression its making over 500 hp @ 6000 rpm on pump gas. Here are the specs on my engine. Good luck.

383 stroker
Eagle forged balanced rotating assembly
Edelbrock E-Tec 200 heads
Crane Gold roller rockers, 1.6 I, 1.5 E
Comp Cams Hyd. Roller 562 L., 248 D., 110 CL.
Edelbrock Vortec Air Gap Intake
MSD Pro Billet distributor, 6AL Ignition.
Holley 950HP carb (had a 830HP but gained +21hp with the 950)
10.50 compression

high test pump gas on the dyno:
563 hp @ 6000 rpm
525 tq @ 4400 rpm

Personally I don't think a 2 bolt main will handle those RPM's for very long making that kind of HP. I wouldn't do it.

I have a 2 bolt that spins 7000 plus with over 450hp.

I bought the RPM package years ago and it was not enough hp! Since then I threw away the cam and intake but kept the heads and had them ported. I got a cam custom ground for my car and Vic jr intake ported also. This is what I am running now. Still not enough power, lol. But I'm one that says "you can never have enough power"!:D
