Make sure you have it pressure tested if you do....n/m

it says right in the add all intakes are 100% pressure tested.

Who elses products do you have to pressure test?

crazy that crap like this gets dumped on the market,

This junk takes consumer dollars away from legit manufactures that test, develop and have 21st century Quality Control standards.

Yeah....

...I'd pressure test it again....LOL

I pressure test everything, including brand new aftermarket blocks.....for a reason.

How much pressure?

June 7 2012, 9:14 AM 

just the water ports or the plenums too?

It depends on what is being checked....

June 7 2012, 9:58 AM 

With a dry intake, probably put 30-50 psi on it, let it sit, and see if it bleeds down. Aluminum is notorious for being porous. Although it's not as critical as a wet intake, it could still cause vacuum leaks...

On the blocks, same deal, but I've found that it doesn't take much to show that they're going to fail. I had an aftermarket aluminum FE block a few months back that was leaking through the lifter bores with 10 pounds on it. Threw some soapy water on it and voila....bubble fest.

Damn, I've wanted one of those for a long time, BUT PC? sorry

June 7 2012, 8:42 AM 

I've been trying to convince Scott Cook for years that we need one of those, not ProCrap beats everyone to the market.

So now what?

am I forced to buy ProCrap? Damnit..

Somebody PLEASE kick Edelbrock in the nads and wake them up. a 2x4 air gap for their alloy heads would be a nice addition to the line up.

for now I'll stick with my BT with the 4500 750 carb.

details..

June 7 2012, 8:56 AM 

looks like it is a open single plenum intake,
bolt holes are slotted for possibly 351W use also?
gasket flanges also look like the might fit a 351W block

what are those front bolt holes for behind the dizzy, or is that the back and those are vacuum ports?

then it has injector bungs cast on it. Why? how many people out here would buy a 2x4 intake, then convert it to Fuel injection? not many...

I don't know,
someone buy one of these so we can test it and convince E-Brock that they can do better....

2x4 for C

June 7 2012, 10:05 AM 

I made an offer that was accepted which will probably become a charitable donation to the C community when I post pics and observations after receipt. Suggest anyone interested in this piece make a low ball offer until it is vetted.

The pictures do make it look like an open plenum single plane with very short runners and very large plenum. It will be a dog if that is the case. Also need to check for carb-carb, carb-distributor, and carb to fire wall clearance as this is a challenge on 351c 2x4 and corresponding compromises must me made.

Best,
K

Powder coat

June 7 2012, 12:44 PM 

Would Powder  coating help with porosity? Since the Cleveland intake is dry I would think that would work. Thouoghts?

Powder Coat

June 29 2012, 2:25 AM 

Powder coat would probably work but may be overkill for the problem. Eons ago when Chrysler was building big performance V-8s , they made some magnesium parts. And if you ever thought cast aluminum was porous.... Anyway, Chrysler Engineering began going down the street to a Rexall Drugstore and buying pint bottles of egg preservative solution, also known as sodium silicate or 'water-glass'. The porous castings were taped up, filled with the solution, drained and air-dried. That's all it took to seal them up for pro-racing, and the excess solution was reuseable. About $3 a pint.

Let us know!

June 9 2012, 9:12 AM 

Kelly, Please post some detailed pics and test results when you get it running!

I suspect, because of it's design, this manifold will be more show than go.

But, with that being said... it should look freakin' cool!

Received it today

June 13 2012, 8:52 PM 

The return address on the box was ProComp Electronics in Rialto, CA. -That puts an end to that question.

I will give a detailed report with pictures this weekend. Looks to me that this was cast so it can be machined to accommodate a 9.5 deck Windsor or 9.2 Cleveland which is reasonable. The Cleveland rear valley rail is a milled not "as cast" feature. All mounting holes are slotted (presumambly for 9.2 or 9.5?) except the center 5/16 mounting bolts which are just drilled.

Port size is not quite 4V C but close. Without measuring, probably matches the procomp C head port position would be my guess. It has some odd features. The floor of the plenum is even with the bottom of the intake port so it literally has no runner length on the floor, a very short roof, that connect to a very large open plenum.

More later.

Best,
Kelly

Please measure the cross-sectional area of the plenum runner openings
and the cylinder head/intake manifold openings, as well as the the runner
length and A/B heights and I'll add them to the simulation database. Or
just bring it with you when we dyno the Fontana and I'll measure it.
If you want to dyno test it, we could probably do that too, assuming it
seals against 2V or 4V ports.

That would be much like an Offy Equaflow 360 but without the divider.
Big plenum, no runner length to speak of and the worst of the intakes
tested on the dyno mule 351C.

open plenum

June 7 2012, 9:14 PM 

Looks like you could do a little fab work and make it into a blower manifold.

I'm with Tony on this one!

June 8 2012, 12:05 PM 

While procomp has some iffy products out they seem to be aggressive in terms of marketing and designing new products. That is a heck of alot more than edelbucks can say and the rest of them! The thing with aggressive companies is they usually get bigger and better. Until the manifold is tested and determined a piece of junk I will give them credit for going where no one else seems to wanna a go. There has been a few companies that have surprised even the crustiest 351c enthusiasts on this forum!

I really don't get you guys.......

I really don't get you guys.......

Who cares that PC made it? I'm just glad to see that someone was willing to step up to the plate and market a 2-4V Cleveland intake. Realistically, what other/better alternatives are there? Had Edelbrock decided to manufacture one I guarantee you they'd do something to screw it up like use 2v ports and/or carb placement so only ED carbs could be used. Almost NO chance ED would have done the job right. Just look at the 2-4V FE intake the produced. All they needed to do was use spacing so Holley or ED carbs could be used and they'd sell more of those than they could make. Had DOVE done it the quality would be no better, probably worse, and the price would be at least triple what PC is asking...

I'm glad to see it and I'm saving my pennies...
