I bought this intake off ebay several years ago. I was told is was a Performer RPM and it obviously isn't but the price was right so I used it. A HEI disributer hits the runner so I'm guessing it's old, and it has mounting holes for both syles of carbs. There are no numbers to be found. I appolgize for the pictures, I know it's hard to tell with the carb bolted on. Any ideas? It serves the purpose but I think it falls info the "perfomer" catagory instead of the "rpm" catagory and if so I might be better off with something else.

I've been looking for a better rpm style manifold, like a Edel Performer RPM Air Gap, Weiand Stealth, or Holley Street Dominator. Are there any articles or personal experiences actually comparing these? I'm not looking for "I own this manifold so it's the best" comments. Thanks for any input!

 

Too much stuff to see it clearly, but I'd say either a performer or 'stock type' weiand manifold.

 

i dont think that is edelbrock doesnt say anything on the runner in front of the carb and doesnt look like it ever did and it would be thier Endurashine which i dont think was out that long ago

 

Might be some type of Edelbrock, but I'd say it's not a Preformer.

 

looks like an older style z28 intake to me does it have the firing order on the front if so its a gm intake

 

you would never get...or keep cast that shiny

 

doe sit say anythingt on it behind the carb or downlow in front of the distributor ?
at all

or anywhere

looks kinda like it bene blasted and polished

but thats just me

good luck

 

No text on it anywhere, including the bottom.

 

There's an odd looking small protrusion over the end of # 1,2,7, and 8 runners close to where it meets the head. You can see it in the second picture. Ring any bells?

 

could be an edelbrock but not a RPM i havent seen those with both bolt patterns

 

Yea, it's a low rise dual plane of some type - like a stock one.
No magnet sticks to it right? It is AL?

Looks like someone took enough time to polish it up, it's seen some lovin' that's for sure.

 

So I'd definately be better off with something else, any suggestions between the three I'm trying to pick from? From what I've read, they are all good, and the Air Gap is more money. Thanks!

 

It looks old, whatever it is. I don't think any intakes (stock or aftermarket) have had provisions for an intake-mounted breather/oil fill is DECADES. That's the big hole in the front of the intake, down low, near the thermostat housing. Your is plugged, obviously, since nobody but the restoration guys use that location for the breather/oil fill any more, but that's where it would have gone.

See how your alt. top bracket is hacked-n-modified to fit onto that intake? That's common when you try to fit newer style brackets onto old style intake.

 

They've always had polished intakes. Endurashine is marketing BS for some sort of protective coating they've recently introduced.

SP2P maybe?

 

I don't think it's a SP2P. Definately aluminum, checked it with a magnet. Any input on my new manifold selection? I'm leaning towards the Stealth, from what I've read I might have trouble fitting the Holley.

 

Looks kinda like a Power+Plus Crosswind Manifold

 

Definitely NOT the SP2P.

Not any of the old factory intakes.

I'm stumped. You're right, it's REALLY old; pre-69 kind of old. Having both sets of bolt holes but the thermostat housing where it won't support the earlier style of RH alt bracket, where the bracket went to a stud instead of a bolt at the pass side of the water neck, puts it between about 65 and 69 or maybe up into the early 70s, before the new style of brackets was important in the marketplace.

 

Definitely looks dual-plane, though, so it's not a Scorpion or a Tarantula. Who else made aluminum intakes back in the day, Offenhauser?

 

Doing some research, is this the "Stealth" everybody likes? It looks like Holley as maybe renamed this one to a "Action-Plus" and now the new Stealth looks like a Holley Street Dominator?

 

It's even got the oil fill tube hole, so at least was intended for a 60's SBC. But it doesn't have the AC bracket holes, has those "nubs" instead - I've seen those nub bosses on factory intakes, but don't recall any use for them. Don't see a divorced choke mount, but that may be hidden. Appears to have the exhaust cross-over.

Really looks like a home polish job to me. Probably ground off all identification marking in the process to make it "cleaner".

I'd guess an early Edelbrock, but that's a pure guess.

 

The "Action-Plus" intake actually resembles the mystery intake that's on your car right now. In fact, that's my guess on your mystery intake. The pic you posted is definitely the "Stealth" intake. My brother runs one on his 69 Camaro, and he's really happy with it. There should be no problem at all fitting a Holley on it either. In fact, Holley bought Weiand several years back, so of course a Holley will fit on a Stealth intake. My brother also used to run a Performer RPM intake, and he replaced it with the Stealth because he had to use a carb spacer on the RPM to be able to hook up his power brake fitting without it hitting his Holley carb. Edelbrock intakes are decent, but personally I've always preferred the Weiand/Holley intakes over them since I run Holley carbs, and they're basically designed with those carbs in mind. Edelbrock intakes are overpriced and more tailored for those junk, re-named Carter AFB carbs that they sell. Before anyone gets all excited over me dissing Edelbrock, keep in mind it's just my own personal opinion.

 

I like the Holley Street Dominator (300-36), but I've read a lot about having to use an old BBC drop filter base with a stock hood to clear. Is this true on an '82 Berlinetta?

 

Yeah the Street Dominator is a tall intake. I'm pretty sure you need some sort of drop base air cleaner.

 

its a Professional Products Power+Plus manifold basically an edelbrock peformer

 

Ummmm....no.

Here's that product; actually called a Cyclone Plus. No resemblance. Unlike the one in question, the PP one fits 69-up cars.

 

If anybody's interested in knowing what I ended up doing, the Holley 300-36 is a huge improvement over this manifold and fits with a 1 3/8 drop filter base.
