Anyone use the new edelbrock intake for lt-1 and lt-4 that is out now?Im thinking of doing the Lt-1 intake swap on my 87 L98 and instead of buying a stock LT-1 intake to alter,buying the edelbrock version.Is there a big improvement in the edelbrock instead of a stock LT-1?Thanks

I guess nobody has used this new intake yet or knows if it can be altered like the stock LT1 intake to fit on a L98!
It seems like a cheap alternative to a mini-ram and better than just using a stock LT1 intake to do the swap.

I have noticed that if no one has any experience with a certain item, no one really speaks up. Like others, I don't like to give false statements or second hand experience. I know nothing of the Edelbrock LT-1 Intake as I have kept my LT-1 completely stock (minus a K&N air filter only).

Hold on now... you have an obscure question- LT1 intake swap.

I have an LT1 intake that I plan on using for a swap one day in the future.

Here is what you'll need-
Remote thermostat
Spacer for he distributor
An AFPR on the back of the fuel rail
You'll need the later style fuelrail
You'll have to block off the EGR
Drill the new bolt pattern
Tap fittings for the coolant lines

If you do it yourself, you'll have a mini-ram on the cheap.

John Millican did a great job -

Thanks for the response guys.I know what it takes to do the LT1 swap on to the L98 but was just wondering if doing the alterations that you have to do to a stock LT1 intake to get it to fit on the L98 would work on this new edelbrock intake.I guess the intake is so new that nobody has tried it yet.I am thinking about doing the swap on to my 87 L98 and i was looking on ebay for a LT1 intake to do all the alterations on when i came across the edelbrock intake.I am thinking of buying the edelbrock one and altering it to fit on my motor,I figure it has to be a better intake than the stock LT1 intake.It has the air gap design kind of like the miniram so i wonder if it is just as good as the miniram.Maybe ill just have to be the giny pig here.:D

If it quacks like a duck...
Walks like a duck...
It must be a duck.

So, yes- the intake swap will work regardless of if it is a GM or Edelbrock. I would suggest that you use the LT1 and run a cooler thermostat- but then again, I'm cheap. You can find a complete manifold on Ebay with fuels rails for around $120.

I don't see the Edelbrock giving you huge advantage unless you just want to be the first on the block.

Not to be a downer, but you will need a custom PROM.

Anyways- it sounds like you have a great concept for a swap- good luck and post pics!

I don't have experience with it but I would think the same way. I mean, both would have to be modified to fit the L98.

The reason why I would think the Edelbrock LT1 intake would be an improvement over the stock LT1 intake on a LT1 motor could possibly be because it's ported a little?

That's just speculation on my part but if that's even remotely true, I don't think spending the extra money on the Edelbrock LT1 intake vs. the stock LT1 intake that you could get on eBay or 'Vette yards would be worth it.

I have a couple questions on this. Why is a custom PROM needed if you use an EGR valve. Does the original distributer fit or do you need a small cap version such as in the pickups ? This really sounds like a fun project and if I can get prints with the proper location of all the machining I can easily do that myself. I have the use of a CNC mill at my disposal.

NICE 'Vette! I also have one of thes and I LOVE it! Sorry for my long reply, but I love CARS AND I love LT-4'S!! I feel that an LT-4 will blow away an LS-1 because I have already done it, even before I added my Supercharger....My '96 Coll Ed. has some light ground effects and the rear hatch windshield spoiler like the old Dodge Stealth had. This spoiler mounts off of the rear glass using the windshiled hardware and againm, can easily be rremoved anytime. But I would never want to do that as it looks awesome!! This beautiful 'Vette was a feature car of the month in 'Vette Magazine for August 2005. I purchased it with only 4,000 miles on it from a friend in March of 1997. It NOW still has only 14,000 miles on it! I just, only 2 months ago, had to finally change the ORIGINAL GM Freedom II battery! It lasted all these years! I did also add a Carroll/Vortech Supercharging system to it that I had professionally installed shortly after I bought the car back in 1997. I first had to blow away a new 1997 C-5 LS-1 before Suprecharging it to prove my point! The light ground effects all are installed w/double-sided tape and silicone so anytime I want to return the car to stock, I can do so easily and there will be no holes drilled in the car anywhere! I might need to buff out the paint however. I am running 10 pounds of boost and using water injection intercooling as well as an MSD Boost Timing Master that pulls out 0.5 degrees of timing per pound of boost so I do not blow up the motor as the LT-4 came with 10.8:1 CR from the factory. I also had installed the SLP Stainless Steel shortie headers while they were still available as well as a full 3" SLP SS exhaust system with the chrome factory-style exhaust tip covers on the back. My cats are still on the car, but they are empty! This car really ROCKS and still, if I take a long trip, it will easily get no less than 26 to 27 MPG even with the 3.73:1 rear axle I installed to help bring on boost sooner, which it definitely does do! The only cars I own that can beat it, not by much though, is my custom Supercharged (roots) 1971 Chevellle SS454 5-speed (yes, 5-speed) that I also originally purchased as NEW back in 1971, and my 1997 custom Supercharged Porsche 911 Carrera 6-speed. I guess you could say that I believe in Supercharging for power! I LOVE it! The next car which I am about to install a Supercharging system on, is my 2002 Acura RSX-Type S. This 4-cyl 200 HP stock motor thinks it is a V-8 since even as an N/A car at the moment, temporarily, it runs like a V-8! If you will go to www.cardomain.com and type in rpalais into the search bar, it will take you to my garage pages and you can view most of my cars. Thanks and best of luck to you and your beautiful LT-4 Coll. Ed!! Rich

To get an LT1 intake on early style block you lose the EGR on the back.

Even if you did get a remote EGR, you'd still need to optimize the fuel and spark tables to get the most power out of it. The L98 tables are designed around the long runner design.
