I just received the new intake from Summit. I'm still waiting on the fuel rail though. Let me tell you, this thing looks bad ***!! A few notes about it though:
-There are no provisions for an EGR valve
-It will not work with the stock fuel rail
-It will not fit the 87-up TPI heads, only the standard small block Chevy heads
I plan on getting a set of AFR heads and a cam (probably the LT4 HOT cam) for this intake. I emailed the guy from Holley and he will be sending dyno numbers on the intake shortly.

 

DON'T WORK WITH 87 ^ HEADS?????

That would suck having to grind out the center holes to get it to fit
Holley missed the boat by not making it a universal fit.

 

Heres the big question: HOW MUCH???????

 

THe intake and fuel rails will set you back about $450. I'm thinking of getting one but it doesn't have EGR provisions which is kind of a problem here in california, and if it isn't even going to fit 23 degree heads....................

 

It's a 23 degree intake,, just has the older / aftermarket intake bolt pattern. It'll fit the L98 Aluminum heads,, just not the 87 up iron headed TPI.

Hey,, 84. It doesn't look like it in the pictures,, but will the in cap coil HEI clear? --- Thanks

 

roc,
I just checked the book, and it will only fit non-HEI distributors.

 

Sweet! I bailed at the last minute and went with an accel superram base. Right now I'm less interrested in being a pioneer, and more interrested in actually getting my car to run right.

 

Here we go again! Now U have to buy a Non HEI distributor. When these people design this stuff dont they have some kind of clue as to whats going on in the real world! A majority of the 3rd gen cars has a HEI on them, DUHH
njdaewoo

 

So the "divorced coil" type distributor will work? (in other words the non-cap in coil type found in 87+ applications) right?

 

from what i have heard about the coils, yes, the external coil dist, will work

 

The stealth ram is only $450 with fuel rails? Did i read something wrong here?

 

Thanks X84. I figured it would need the small distributor like most "tunnel ram" intakes. I might see what the bone yards want for the small external coil later model distributor. Proform has one for around $160,, worse come to worse. Also looks like it might to need an angled spacer for the throttle body for any chance to clear the stock hood. Still,, it is very impressive,, design wise and for the money.

Good luck with your build.

 

I just ordered mine this morning. I've had my car for 8yrs. and I think this is the first time I've spent this much $ on a newly released/ unevaluated part. I'm usually not this daring- normally I let someone else screw up and then learn from it, but this time I just hads to have it. As far as the divorced coil dist. goes...if you're going to run EFI then you are insane not to take advantage of ESC. The benefits easily justify the small extra expenditure.
***Got my Stealth Ram for $279.99 and fuel kit for $173.69 from Summit. Both parts are special order and currently take approx. 4 wks. to arrive***

Keep us updated CamaroX84

 

This is a bit too good to believe... an aftermarket intake at an affordable price? Im sure the price will go up once it really gets out on the market.

 

88 WS6 Trans Am GTA-
You must be as paranoid as I am. That is partially the reason I decided to jump on this RIGHT NOW!!! I plan on running a DIY Prom, so I've got a lot of learning to do. I beleive the rewards will be very high. Holley Tech line told me there is plenty of meat on the intake runners to do a healthy gasket match. In my book... that translates to: We built this to be a real performance intake- not just something cheap to bolt on so you can look different. At this point my only disbelief is that I have to wait a whole dmnd month to get started!!!!!!!!!!

 

Yeah Im quite paranoid! I plan on jumping on this ASAP, just need to get the money together. It wont be something Ill acually be able to use in the near future because I need all of the other parts to finish my engine, but I figured I had better get it at this price before its gone...

 

I just now ordered mine 3.83 seconds ago. I don't want summit to raise the price on me later, and i figure if i don't want it then i can always send it back.

 

i just looked at yearone.com , and their price os $2100 bucks,am i missing something here? or if since you already have a fuel injection setup do you order a different package?

 

can someone give me the part #'s for the intake and the rails?

 

Year One only sells it as a complete kit with the Commander 950 FI crap.

 

Its been posted 1,000,000 times already... I guess I'll make it 1,000,001

Intake is 7540 or 7540P if you want the polished version (which of course costs more... like 250 bucks)
Rail kit is 534-185. I have no idea what you do about a FPR. I'm thinking it doesnt come with the rail kit and I dont think the stock one is gonna work.

I am also thinking it wont fit under the hood of your bird. I wanna get an exact number from Holley on the height, it might clear on the car I plan on putting it on. If it will, I will order it and see if it fits my TA first if someone else hasnt tried it by then already.

 

yeah i ordered mine a couple days ago. CamaroX84 what the hell do you do about the FPR? do you have to buy a aftermarket one or what since you already have the parts in hand?

 

My buddy did a RamJet 350 install on a customers IROC a few months back and the TB on the RamJet intake hit the hood on the IROC. A little work on the bracing under the hood took care of that, but I don't think anything bigger will fit in there......

Keep us posted guys.

 

sorry guys,try to bare with my questions here-im new to fuel injection,so im still learning .I looked at the stealth ram intakw on summit with the part # provided (thanks madmax) and since its on back order they wont let you look at details.But it just says TPI manfold as the part-so id that just the base or is it the base/runners/plenum/throttle body?I know you have to buy the fuel rails seperate.I thought it was for the whole setup,but.

 

Theres no separate runners. The intake number I posted is the base and plenum, thats the way they sell it. You'll have to use your stock TB.

 

the intake is 1/2" taller and is level front to rear. the stock intake is slanted lower in the front. they have a kit number 9900-172 that has the rails, crosstube, regulator, and the AN fittings. you will need to make a line to connect to your stock lines. the rails are from their commander line of efi stuff.

 

The rail PN kit is NOT 9900-172. That is for a single plane manifold. The rail kit is 534-185. It comes with the correct rails, crossover tube, fittings, mounting hardware, and 43 PSI regulator. It has -6 fittings for supply and return and comes with barbed adapter fittings.

I know this since I created these pns for Holley .

It will be a very close fit under a stock third gen hood. I am going to check it soon hopefully.

Also, these parts are readily available from Holley. They are not on "back order" from Holley at this time. They just aren't in stock at some retailers. Most places give some std. reply such as 4 wks etc. if it is a part that they don't stock.

Hope that helps.

 

so is the afpr just like the tpi one or different? And if its different is it adjustable?

 

Doug, it's nice to see you made your way to thirdgen.org. Welcome aboard!

 

since you created these pns for holley, then tell them to quit giving out the wrong ones when someone calls.

talked with tom at holley today. the intake is 1/4" taller than stock. it is level from front to rear. he said the stock fuel rails might actually work. if not then 9900-172 is the fuel rail kit. comes with fuel rails, regulator, AN fittings for fuel lines, and crossover tube. will need to fab line to connect to stock fuel lines.

i posted this a little while back. but as usual, you talk to two people and get two different answers.

 

I am almost positive the stock fuel rail will not work. The stock rail uses bolts that run vertically through the rail into the top of the manifold base. The Stealth Ram uses bolts that run horizontally across into the side of the intake. My fuel rail should be coming on the 17th of this month. When I get it I will let you guys know about the regulator issue. I should also be receiving another email from Holley soon, including dyno numbers with the Stealth Ram. I will keep you guys updated. I Hope this helps.

 

Thanks! I just ordered the Stealth Ram. I talked to the guys at Holley as well. They said the stock fuel rail may work. You might have to fab some brackets to hold it down. Have you tried the intake in your car yet? Just wondering about hood clearance? If you can keep us updated with your progress that would be great. Thanks man!!

 

The FPR is not adjustable. It's the same that come on other Holley SBC and BBC systems that are adjustable. I believe its the same as a Buick GN regulator.

If you guys have any tech question on Holley EFI products, just post over at Chevytalk.com. I moderate the EFI forum and see posts everyday. I don't get over here as much. I am an EFI Engineer at Holley and can answer any EFI question you have on their product. The tech guys have a tough life, they have to answer questions on Carbs, EFI, Intakes, Blowers, Cams, Heads, Water Pumps, Pistons, Rods, and Cranks. Though I'm never happy when misinformation is given.

 

I tried ordereing the polished version but Summit does not have that part #7540p. Summit also said #9900-172($199) is the fuel rails and the other # 534-185 is just accesories. I ordered #7540 and 534-185. I would also like to order the polished version. Can anyone tell me the difference between 534-185 and 9900-172 since Summit had no info on the setup?

 

9909-172 is a fuel rail kit for manifold PN 9901-101-1. It is a 4 bbl single plane style EFI manifold.

534-185 is the fuel rail kit for the 7540 and 7540P.

It contains 2 fuel rails, regulator, crossover line, fasteners, and -6 and barbed fittings.

Don't listen to anyone else!

 

yep never listen to the techs at holley when they give you a part number. hell when i talked to tom there at holley he didn't know the new part number to the stealth ram was 7540. he gave me a different number. so, he asked where i got the 7540 number and i told him from this site and summit. and i asked him about the 534-185 number. he wasn't sure about it. so he gave me the 9900-172 number. by the way the regulator is set at 43 psi.

not picking on you doug. it's just typical that when you call a manufacturer and get two different answers. but, in tom's defense, he did say he wasn't real close to the r&d on the manifold.

 

Hey Doug, how about creating a 50-state legal version of the Stealth Ram for us CA folks. Or if nothing else, just make one with EGR so we can fake it.
And say hi to Chad Cassetty for me.

 

I just ordered mine with summit, got the manifold as well as the fuel rails. Hope it gets here soon enough, the car's going to be all ready to go and waiting for it.

 

<-----just waiting for his stealth ram.....

 

I just ordered one too. Wonder if the 1994-97 throttle bodies fit on them. What is everyone planning on running for a small base distributor (MSD, Holley, etc)??

J

 

Since you can run a TPI throttle body on an LT1 intake, I'd assume you can run an lt1 (edit: )throttle body on the stealth ram.

I've got a gm hei divorced coil dist that I'm planning on using with it.

 

The TB should bolt right up, but I am wondering about the thottle bracket and the distance between the TB and bracket. I'll measure it tonight and see what's up.
Does MSD make a small base HEI type distributor?

Thanks,
J

 

Uhm... running an LT1 intake on a stealth ram? Did you mean LT1 throttle body? It'd be quite a feat to run two intake manifolds at the same time!

 

Er yea, I think you could run an LT1 throttle body on the stealth ram.

 

i just got this in an email today from holley i thought it might be helpful for some of you.

"As of right now we have not test fit this on the camaro. Hood clearance
may be an issue. The unit is 10 inches tall which is about 1 1/2 inches
taller than the stock manifold. The stock electronics should work as long
as you do not have the cold start injector. The fuel rail kit does include
the regulator and it is adjustable. The rpm range is idle-6500. Thanks"

 

OK, So when I call Summit Racing tomorrow to order this thing, what part numbers do I need?

Is it:
Manifold Kit 9901-101-1
Fuel Rail Kit 9909-172

Or is it:
Manifold Kit 7540 or 7540P.
Fuel Rail Kit: 534-185

Thanks!

 

My original question to Holley:

First off i have a zz4 in a 91 camaro with all the stock tpi. First question is will my 91 HEI dist. fit (the stock one that came on my camaro). Second is will my hood close and if not how much more clearance do i need. Third is i have a holley adj.fuel press.reg. for my tpi can this be used on the stealth ram fuel rails or do i need a special one. Last question is I only need the manifold and plenum and fuel rails correct ? or do i need somthing else special.

The Answer:

They are currently checking the hood clearance issues with this manifold and a stock hood. It will accept the stock hei distributor. The stock regulator is different from the one in the kit. If you order the fuel rail kit you will get an adjustable regulator. All you should need is the fuel rail kit and the upper and lower manifold. Thanks

 

What about a strut tower brace? 2pt or 3pt looks like you dont even need to measure, just toss it out.

 

yes what about the stb? anyone know if it will fit?

 

I highly doubt any production STB would fit, but I'm planning on fabricating something after i get the stealth ram installed.
