Look at this intake i found on Ebay. It still needs to have the water outlet reworked. I think the EGR setup and factory dist hole is very trick.

One more try on the pic.

u r sofa king we tah did

WTF, who made that.

n/m

looked closer, its photochopped

No, its an early LT1 prototype, from before the Optispark was sorted out. You see them on eBay every now and then. Made by GM for engineering use.

u r sofa king we tah did

no that is a photoshop job. why in the world would gm put 2 egr ports. and the blend to match in the other egr port isnt too great. photoshop all the way.

Have you been asleep for all the LT1 threads?

One side is the feed tube from the exhaust manifold (the way the LT1's have always been) and the other side is the valve itself. Look at any Corvette, Edelbrock, Accel tpi base and they all have "2" ports since there are no EGR passages in the head.

The blending is because the manifold was rough cast and hand blended. But nevermind...

I've talked to a few LT1 guys who've mentioned the illusive LT1 intake W/distrib hole. As far as I know it exists.

I have seen them before I have been trying to track one down for about 6mos. now. I posted on camaroZ28.com and no one knew what I was talking about. I would love to find one of these and run vette heads.

tpi_roc

If you find an abundance of them be sure to let me know

poncho9789

Will do I have looked all over and people tell me that there is no such thing and others tell me that it was just a myth. But I saw one on a guys website and haven't been able to find one sense. When I ask about it everyone tells me it is a carbed intake that I am talking about

tpi_roc

You know.....

I think i actually heard that "rumor" that its a tbi/carb intake

Let me do some searching and see if i can pull anything up

but if it was carbed why do i see fuel rails?

poncho9789

They were telling me that the intake was the one that gm sales that is for putting a carb on a LT1. Scoggins Dickey sells it GM part number for the carb styles are as follows:

LT1 carbed intake 24502592
LT4 carbed intake 24502574

Interesting..

Just looked it up, they sure have it, wonder if you could modify a mounting bracket for a TB then tap holes for fuel injectors

This is the picture from the ebay auction.

The intake is a prototype look at the bolt holes all of them are at 72 degree angle with the 1st gen bolt location very strange.

The only number on it was RR 9287

Anyone know more about this intake.

Those pictures are two different intakes. Do you actually own one of these? If so, what did you pay for it?

JERRYWHO

Both pictures are the same intake. The picture with no fuel rails is from the ebay auction i won mid last year and the picture with fuel rails is what it looks like today.

The intake has had the throttle body relocated up .850 for more room to mount a thermostat housing on the front and the rear was notched for the fuel crossover. Also the intake ports have been raised .250 to match up to a set of pro-action 220cc heads.

The amount was $150 for the auction.

Still the question is any one have info on this intake.

One other thing you can see it has the 3rd gen EGR not the LT1 type.

Sorry but its real, I've seen it in person with my own two eyes. Jerry is the guy doing my runners that I posted about. He is an excellent machinist, he knows his stuff. He wouldnt try to BS anyone with a photoshopped picture.

Steve91Z28 L98

Very nice. I'm impressed with what you've done with it. Do you have any more pics of it from different angles? So this intake has the standard bolt pattern also? Another question: Does water flow through the front of the intake? I'm interested in how you plan to make the thermostat housing. This is a very interesting thread.

JERRYWHO

Hi Steve

The intake was standard sbc bolt pattern when i got it. The bolt holes had the 72 degree angle on all of them not just the center two. After a weld up and redrill now it's bolt on to any standard small block. The next problem was the heads that i have the intake ports are so tall ( 2.250 tall ) that the port had no sealing area on it so we just welded the intake one more time and now it fits with a good amount of gasket area. The last problem on this was the water outlet. I was going to do it the same way you guys did but i wanted the factory look so it's move the throttle body up and install the t-stat on the front. It's all most done than just a trip to the powder coat shop and finsh mill all the gasket serfaces and it will look factory i hope.

How did you move the TB up and I like the NOS set up what did you use to do that as well.

JERRYWHO

To move the TB up all you have to do is mill, cut, form, weld, grind and sand blast and its done.

The nitrous kit is the same one that is installed on top just mounted under the intake so the motor looks a little more stock. It will be setup for 200hp and the plate stage at the TB will be 100hp for a total of 300hp of spray.

Added a picture from last year before the sand blast job on it.

Nothing like seeing a nice RARE factory prototype manifold with thousands of man hours of engineering work go down the toilet to be hacked up. Jesus thats the worst modification job I've seen in years.

I think I'll go puke now.

Oh, is that all? LOL
It looks like more work than an LT1 intake would have been. I'm sure it will look great when you are finished. Don't forget to post pics of it in the car.

afgun

Well, GhoSSt, you know what they say about opinions...

I happen to think it's a great job, and wish that I had access to one myself!

nblanchard

well, wasn't that rude of that ghost guy... I don't think it looks the best, but at an engineers stand point, I think you've done a great job... besides. this engine will probably pull just as hard as a miniram setup. Good work.

Probably, but I'm not here to cuddle up and be sticky sweet. I'm here to learn and if possible, maybe pass something on.

Any engineer with an iota of skill would demand imperical, factual data before declaring "great job".

Not to mention the fact that rare engineering parts often fetch thousands of dollars a few years after the fact.

afgun

If you're interested in some "rare engineering parts" then have I got a deal for you... I have some GM large-tube runners/siamesed plenum and base (non-siamesed, used a file to open the bolt holes) that I'm taking off the car for my superram install. Wanna buy 'em ? *G*

cheese_kake

I just had to post on this because, this is the first post in 4 years LOL!!
But that is a pretty trick intake.
