That thread on the merits or lack of regarding Edelbrock cams/equipment went on ..... and on.... still it was interesting to read comments and opinions. I'm not going to start in again. I have wondered about the performance of the Edelbrock RPM cam myself. I have not read or talked with anyone who has actually run that shaft & lifters, springs, etc. On paper it looks good but lots of cams do on paper right? As for the basic Performer cam I know that it was designed as nothing more than an "RV" grind for a all around driving providing torque to 5,000 rpms.
As for the Edelbrock Performer intake I can tell you that I personally had excellent performance provided by it. That's in comparison to two other intakes that I ran on a 428 Cobra Jet in three different vehicles (I just seem to love pulling and placing engines....). I ran four different cams in this exact same engine. No dyno testing available, just real world on the street and strip comparison.
First, Stock CJ with Chet Herbert grind which I can't remember exactly what it was, it has been sixteen years now, but Chet personally recommended it being a cam that would exceed the stock C6OZ-B and make h-power to 6,000 rpms. One thing, Herbert cams at least then were regrinds thus very economically priced. Intake was a '67 PI with original Holley 735. Results: Good. Car ran best of 13.52/103 mph. This with 4.11 gearing/C-6 in a '66 Cyclone GT. Drive it to the strip. Uncork dumps and let it run through the stock CJ ex. manifolds. I didn't think the cam was good enough! Another problem that I have.
So in goes the at the time brand new Rhoads 222 cam/lifter kit. This was supposedly the hot ticket in '86. It was winter. It was snowy so why not do a cam change? Oh, I also ran stock Ford 1.76 adjustable rockers rockers throughout all of this personal research & change. I wouldn't call it development. Especially after the results of this cam change.
The Cyclone would now run a 13.9/100 or 101mph. No other changes! Aren't I the smart guy?
At this time I acquired a mint '61 Starliner w/292/cruiso. One owner car that I bought right and just thought I'd detail 'er and sell 'er. What I told my wife.....
Well I decided the big 'liner was better than the Cyclone. It was just a personal choice at the time. Out comes the 292 Y block and cruiso. Cyclone yields the CJ powertrain which did include a CJ - C6 (R code servo and cast iron tail shaft). Easy fit into the '61. One little change was that I did install a TCI street dominator torque convertor. Engine remained exactly as it had been in the '66 Comet.
Results: 13.90s/low 100s....this with a car that was 200 lbs. heavier. Maybe the convertor helped? Whatever, I still wasn't happy. I wanted those consistent mid 13s back. The Herbert cam was now in a friends '63 390. So now what should I try?
Schneider solid lifter. No changes, just their 427 grind & lifters. Again, I can't remember but it was something like 230ish both intake & exhaust @ .050. Results: Whoa, this cam worked well! It would easily pull to 6,200 plus but ran my best e.t.s were to column shift the mighty C6 at 5,900 rpms. The big Galaxie ran a best of 13.72/103 mph. This through shorty HP352/360 horse exhaust manifolds and the exact same dumpouts I'd ran on the now gone Cyclone. Gearing? Everything from 3.50s to 4.56s. The 3.50s were all around best with this powertrain combination.
Next, a friend loaned me his old Offenhaeuser dual four intake. This thing looked very nice with a couple of ancient AFBs and the coolest Offenhaeuser alumiunum air filter. I wouldn't run the spider infested '58 Pontiac carbs so I bought a couple o'brand new Edelbrock 500 CFMs with manual chokes along with E-brocks dual carb linkage kit. All went together easily and basically. It looked so cool on the big CJ which had the original plain aluminum Ford finned valve covers. But performance? Get ready......13.9 once with mostly 14.0/14.1s. I apparently get a real kick out of slowing cars down. But it looked good. But it didn't run as well as the PI/Holley 735 or even the single autolite 4100/1.12 I ran once in awhile for fun.
Time to pull that engine! My '68 F100's original 360 was getting very tired. The '28 CJ would make a nice power source. First though I wanted to make a few changes to prepare the mill for the work horse F100. Off comes the cool lookin' Offy. Out comes the Schneider/solids. In goes Ford Motorsports one and only cam for the FE. I chose it because it "looked on paper" a little better than the stock GT/CJ/PI cam. It was available cheap. I topped it off with a brand new Edelbrock Performer intake & Edelbrock 750 manual choke carb. The RPM intake was not available yet and I doubt I would have chosen it for this anyway. This was to be for an everyday hauler.
Results? Whoa! This engine had never put out so much power/torque right off the line! Obviously it couldn't help but being a tire ripper. A stock 428CJ rips 'em very well especially that first to second shift with a C6 has to be experienced to appreciate. But I'm telling you, this Edelbrock intake/750 carb(I did have to tweak the 750 with larger metering rods & weaker step up springs from the Edelbrock strip-kit, and a guy at Edelbrock personally advised me as to what to do about the initial bog I was getting). Anyway, this Induction system & that mild cam would literally overpower the M & H DOT Street /Strip tires I had been using. With the other combos I would just power brake to 2,500 and stab to the floor with the last amber on the tree, then steer and shift that old column shifter twice. I ran easy 14.0s/99/100mph with this Edelbrock intake/carb & the very smooth idling Motorsports cam.
So what does this mean? I don't know really except I personally like Edelbrock intakes & their carbs. I would like to run their complete system including heads, RP |
