FE Performer RPM "knock off" intake?
« on: March 14, 2025, 03:00:40 AM »
Looking into using an Edelbrock Performer RPM intake on my 428. I am seeing a lot of Ebay listings for an RPM "knock off" intake in the low $200 dollar price range. Anybody use one of these yet?

I will be replacing an original Holley Street Dominator intake as I believe the Performer RPM is better intended for my purpose. Any thoughts?

Thanks,
Brian N

There is info on the site, buyer beware mostly.  Basically, if you get a good one, they work well.  However, some don't have passages drilled, some are crooked, and of course they fund a country we are trying not to be reliant on.

Second, my experience is that there really isn't any magical gain of an RPM over a SM, especially if you do the Edelbrock mods to the SM.  However, unless you can port yourself, likely cost more than the Chi-intake.

Holley Street Dominator is better than the Edelbrock Streetmaster, totally different intakes.  The Street Dominator's plenum is not made like the Streetmaster.  Joe-JDC

Thanks Joe, read it as SM but clearly Holley SD.  As they say, RTFQ....I really like the Holley intake too, even more reason to not buy offshore IMHO.

If your interested in changing your intake. This is what I would highly suggest you buy first:

In it 3 different 428 engines are tested, using 20 some intakes. There are also 3 more FE's engines tested, from 427 to 492 ci

Love that book, lots of great information!  I can't imagine how many man-hours were expended doing all the testing and documentation.

I had one of those Holley Street Dominator manifolds on my 68 Mustang F/B 390 4 spd.

CJ 735 cfm Holley up top, CJ iron exhaust manifolds, and 3.25 gears out back.
Comp 268H cam and 1.76 Melling iron adjustable rockers.
0.030" over Speed Pro forged pistons.
Heads were garden variety passenger car 390. (Not real sure, they did have the 16 bolt exhaust pattern, could have been CJ? IDK)
Back then I was not aware of all the different castings so I don't know the casting #'s.

That engine was a stout performer (sorry, no time slips or dyno data).
The butt dyno says it was pretty quick and had excellent street manners.

Sadly the car and that engine are long gone... much to my everlasting regret...

My opinion...
The Holley Street Dom is faaaar better than any chinesium RPM knock off.
Keep it, and spend the money elsewhere...

Every 20 minute job is 1 broken bolt away from becoming a 3 day ordeal.

I just ordered one of those books, hopefully there’s pictures so I can read it.  I have the Edelbrock SM on a 428 build I did. 530hp, 600ftlb.  I only dynoed with the one intake, which I’m regretting now.  I had a street Dominator, and a few other options.  I guess I’ll never be certain I made the right pick.  I’m happy with how it turned out, it will work fine I’m sure.

I appreciate all the responses! I don't have a problem keeping this Holley SD intake. It is installed in non ported form. Can I use it successfully out of the box, or should I opt for porting? It would seem that if I opt for porting, I would need to weigh in cost factor of the porting and shipping. Might get into used Performer RPM price territory? And, just so you know, I am running C6AE-R heads.

I haven't given you folks any build data on my engine, and I will if it helps? But my goal for the engine was a decent mannered 428 with 425hp and 500 lbs tq. The car it's going into is a 69 Cobra formal roof clone.

Thanks,
Brian

More engine and car info the better.  Additionally, it's always good to free up a little movement but that intake will support that power level.

As a side note at this point, I did some poking around and found a nice undamaged Performer RPM intake for sale in California for $180 shipped! Seems like a really good deal! I mean, new ones from Jeg's or Summit are currently $700 dollars. I'll buy it and use it for a future project, don't think I should let it get away.

Does it actually say "Edelbrock Performer RPM" on the manifold?  The knock-offs look VERY similar.  Is it close enough you can pick it up rather than ship? You know what they say, "If it sounds too good to be true..." Be careful!

It is a real Edelbrock Performer RPM, not a knock off. I can only guess he has priced it the way he did due to the low price of the new Ebay knock off manifolds? Regardless, I'll get some more info. If I move forward with the deal, I would pay him with Paypal but not using friends and family. At least that way I'll have recourse if the deal goes south.

Oh, forgot to mention that I cannot pick it up. The manifold is in San Francisco and I'm in Columbus, Ohio.
