Lots of people on this board have expressed their dislike of the RPM camshaft, saying that it has no low end whatsoever and acts like a dog on the street. I have heard good things about the RPM heads, however from what I have heard you would do well to find a somewhat smaller cam (Comp XE268?). Making 400 horses shouldn't be too difficult.

If you get the "package", get rid of the cam and replace it with a Comp Cams 262 or 268. I am only one of many who have run the RPM setup and hated it on the street. Its lack of bottom end and poor idle qualities are too much to live with.

I basically have the RPM Performer package on my big block with the NOTABLE exception of the CAM (heads and intake are great!!!).

LOSE the CAM and you will be fine. IMO the Performer RPM cam is not spec'ed correctly and you could do much better with one of the suggestions already made. As for me, I chose a Crane Roller CAM.

I ran the heads,intake and carb on my sb with a comp292 cam.I switched over to a Holley 750 vacum secondaries and gained a .1 at the track.I now run the heads with a Victor Jr intake on my bb and love it.
FYI best time with the sb was 13.2 through exhaust in a 2nd gen.

Hey sr71bb.... what specs you have on the new roller Crane cam? I have the RPM heads on my SB with 270mag CC cam and they are great. I am now interested to build my BBC and use the Edelbrock stuff. I see Edelbrock claims 540HP with their kit for BBC. do you have oval or Rect RPM heads?
The Edelbrock RPM cam for BBC is : 240/246 with 560/573 on 112LC. Can you comment on your new cam specs? How does it run on street? What about vacum at idle? Thanks.

Not to rehash this old post but I have a current update on my RPM packaged engine. It runs like a top, idles at 900 rpm, power brakes work perfect.

I have to say it is a good strong engine and well worth the effort.

Glad that this package is working well for you. What stall speed converter are you running?
I have a friend with the RPM cam/intake on a 350 and the low end is pretty soggy.

I too have the Edelbrock package on my 68 Camaro and love it. It idles at 800 RPM and has 11" vacuum. I do have 4.10 gears, which may help. I also have a 2500 stall converter in my TH350 tranny.

I think thats the catch. Automatics! The RPM setup, with a manual tranmission really hurts performance.

I have a Dynamic 3200 stall conveter and 3.31 gears and it drives just like a new car off the lot.

RPM Heads are terrific (have used five sets of them on different cars), RPM cam sucks (with a manual trans, anyway).
