RE:another point of view

That word "moderate" is key. It's also up for interpretation. What's moderate to you might be approaching radical to another.

I know that many have expressed their opinions on the virtues of the RPM. I'm one of them but I'll admit that I have not run an E'brock FE RPM, yet. My opinions are based on reading E'brock's publicity and reading this tech forum.

It's my understanding that the RPM is especially suited for 1,500 to 6,500 rpms. A nice broad range indeed. But it takes the right camshaft and a coordinated, well planned out FE build to get the all the benefits the RPM offers.

Moderate? It really depends on two things to me. First is the weight of the vehicle and then the intended use. A Galaxie approaching/exceeding 4K lbs. or a pick-up that will exceed 4K, running a mild low 200's @ .050 duration camshaft; street/highway driven, would benefit greatly with the Performer. The Performer is designed/proven to work very well from smooth idle to 5,000 r.p.m. I'm reminded of that old classic automotive terminology - "Recreatiional Vehicle", er RV.

I've told the story before and the good thing is that I'm getting more succinct with my personal testimonial to the Performer.

I ran a Performer on a 428CJ installed first in a 3,800 lb. '61 Starliner, then in a 4,100 lb. '68 F100 2wd. I also ran E'brock's 750 CFM manual choke carb on this intake. The cam I installed at the same time as the Performer intake was Ford's one offering from their Performance Parts program(the name of which I can't ever remember because it seemed to change so often). This cam is mild/moderate. Somewhat similar to the GT/CJ C6OZ-B cam. It idled very nicely at 650 and was all done by 5,700. This induction system worked extremely well. There was a ton of off idle torque/acceleration. And that torque we love from the FE was there all the way to 5,700.

Currently, a friend of mine is running a Performer/Motorcraft 4V(Not a 4100 Autolite) on top of a moderate 428 in his '76 F150 4X4, C6/3.50 gears. He is very pleased to say the least. This pick-up is used primarily for recreational purposes, i.e., huntin' & fishin'.

All that being said, would I buy a Performer today over an RPM? No. I don't think I'll ever run a moderate cam again in an FE. If I do run a moderate cam it will be a GT/CJ C6OZ-B topped off with the mighty iron brute...the CJ intake. A concours GT 390 or CJ 428 car. But I've never been a concours guy and I hope I never am.
This thread, so far...
