People seem to forget that this first attempt was actually a longer runner intake. It seems that when people mention the never released Edelbrock intake, they don't realize that it really was quite different inside, unlike the current new offerings. Would have been really neat to get a hold of one of those early attempts.

interesting. so did it actually make it into production, or not?
or maybe it just wasnt a big seller?

i remember it being advertised for a while, in magazines, i think, perhaps i just saw it in their catalog... i dont remember.

i think it claimed to improve the mid range, and perhaps the upper ranges some...

Because of the "Air-Gap" I would think the manifold is higher.

Does it fit well under a C4 hood?

Probably just less plenum volume

I would highly doubt it's much (if any) higher, and there's no way you'd have hood issues, think about the f-body that it fits too.

I don't think it made it to retail, but I did see one with my own two eyes so they evidently made some preproduction ones at least. I remember that at the time I was waiting patiently for it's release, or at least some tests, but none ever surfaced. I do remember that they were making more of a torque claim (I think 30 ft/lbs over stock) rather than a hp claim. Makes sense considering the design.

It is basically an LT4 manifold. all extra casting material underneath and between the plenum and runners has been removed.

Edelbrock does say that the runners are .25" longer, for what that's worth.

Hopefully Rich or Mr. Dave can measure it and see.

At little late getting in on this.....Sorry! Was in a pissing match earlier and got distracted, what can I say?

Right now I'm a little confused regarding getting gains out of anything other than porting the stock intake. My problems is I did two things at the same time (sheet metal intake and stepped headers) and have run into issues that perhaps I shouldn't have run into. (really do know better.....do as I say, not as I do)

However, so far much to my dismay, haven't gotten anything close out of the intake that I was expecting. Went back to my old headers, going to put new springs in the car and give it another shot. Having a very difficult time believeing there isn't more power to be had out of intakes.

Keep workin on it.....maybe it's just me not being able to find it. Hope you have better luck.

I will post some photos of them both tomorrow for comparison's sake. My stock intake has been ported, but runner length and plenum height will be an easy comparison.

Sorry for the delay. Here are some photos of each side by side for comparison. The plenum in the Edelbrock is actually a little wider at the top as you can see in the photos. There is not much if any difference in overall height. The runners do indeed appear to be about 0.25" longer than the stock unit. Anyways...here are the photos:

with the new edelbrock peice being a little wider than stock, will fuel rail covers still fit in place as before?

They appear to fit in the same location as before. If you look at the mounting pad, it is the same. The difference occurs just below the pad where the Edelbrock is wider. It looks like the injectors will be closer to the side of the plenum, but I don't see a problem with the fuel rail.

Resurrecting an old thread. Trying to find out if the ported Edelbrock LT4 intake made any power gains. RichS do you have any post dyno or opinion. Anyone else have any experience with a ported Edelbrock LT4 intake?

Power gains are made with sheet metal intakes (i think forced induction guys pick up 80rwhp) and single plenum (Ie. Like a carb) intakes.

I wouldnt count on porting or anything to this kind of intake To do anything for you.

Would like to see a composite intake for ltx....

I too would like a composite intake! With as many LTx aftermarket heads that are available, you would think someone would have one out by now. F.A.S.T. I'm thinking of you!

noone would pay for one imo
Fast intakes are well over $800 plus the little stuff to make them work (think complete mini setup)

If you got the motor to support it you can make plenty of power with any ported LTx intake. Dont understand the hate for this piece Ive seen them up close pretty nice imo!

There are LT1 f-bodies running 10's on stock intakes. No need to reinvent the wheel. Although a composite design would be nice, just to get rid of the heat soak.

Are there any advantages of the Edelbrock LT4 intake as opposed to the factory LT4 intake, other than the fact that it's a little taller, and supposed to help generate a little more torque? I guess what I'm asking is, is it worth the money to replace the factory intake on, let's say my '96 LT4, with the Edelbrock version? Thanks in advance!
