I am looking to put the Edelbrock 2098 - Edelbrock Power Package Top-End Kits with the Edelbrock 1806 - Edelbrock Thunder Series AVS Carburetors and the tech guy at Summit says this will not fit under my hood?

Anyone on this forum done this and can you confirm this?

Thanks

This is currently a stock L48 engine 350 5.7L
The engine is already out of the vehicle so I cant measure from the intake to the hood.

I think the Air Gap is the killer. A normal Performer or Performer RPM works with a dropped base air cleaner. The extra height for the air gap keeps it from fitting.

I'd say yes.I have Performer w/Quadra J.Unless the new carb is taller.Worst case ,new hi rise hood!! Dont let clearence issues hold you back.

I have the Edelbrock Performer RPM heads and intake, fits under my '79 hood (just) with a drop base and 3" filter. Not sure how the '80 hood compares with the '79? I have a Fitech fuel injection setup rather than a carb.

Not sure why this keeps being said, but the Performer RPM and Performer RPM Air Gap are the same height. Just check Edelbrocks website if you don't believe me.

They even have a specific note on the Performer RPM Air Gap page: "Manifold height: A-4.20", B-5.25" (same as #7101); Carb pad height: 4.72" - the 7101 is the Performer RPM (not Air Gap).

The Performer (not Performer RPM) however is definitely shorter.

And here's the note from the Performer RPM page .

1980 vette here with 355 sbc , 2701 intake holley 670 Avenger carb, 3" drop base with a 3" K&N filter. the top is a Ford style flat top and it all just fits under the hood.

I asked the tech services people at Edelbrock why their web page and technicians state most of their manifolds will not fit under a stock Corvette hood. Their answer was simply that they base their measurements using the OEM components including the air cleaner with a wing nut on top as a standard. They agreed that using non OEM air cleaners may provide the clearance necessary to fit under a stock Corvette hood, but they can not guarantee it.

I have GM crate, with Edelbrock 'vortec compatible' Performer manifold, Eddy Thunder AVS 650 carb and 3" drop base air cleaner on my 81. It fits. Not sure how much extra room but it doesn't hit.

As a few people have mentioned on these threads before: switching to a solid motor mount (if you're doing a top-end kit and dramatically increasing your engine torque with 40 year old rubber motor mounts, now is the ideal time to replace them) will net you some additional hood clearance and stiffen up the C3 frame.

-If you're doing motor mounts anyway and you're going with an intake and air filter+base setup that's "iffy", going with solid mounts might be good "insurance".

And as above, it does fit under the standard hood on my '79 corvette (and many others on here). I have solid engine mounts and a drop base filter, but it fits.

Well I talked to the Edelbrock Tech guy and he said he cannot guarantee the 2098 (RPM iNtake) package will fit. He suggested I swap out the intake specified in the package and swap with the 2101 intake. I lose about 35 hp but I am going from 195hp to somewhere over 325-350 which is plenty for me. I just want the car more fun. So when I called Summit- gave them the info and in the order they switched it for a small savings.

Thanks for all the input on this topic-

jim2527

Ok....so. Go with the 2098. If the hood doesn't close then pay out of pocket for the 2101 intake and sell the air gap on ebay. At most it'll set you back $150-ish. For an extra 35hp I'd take the chance.

I have this manifold no sure model #. Street Demon carb drop base air filter 3inch filter. 1980 hood even have half inch riser to clear linkage. Hood closes but, I dont think there is much space left nothing touches though. Good luck. I posted pic in my album can not seem to post here.

NewbVetteGuy

I think he already made his decision.

I would tend to agree with you- heck couldn't you just shim the hood latch with a couple of washers so it latches, just a bit higher than normal and gain a small bit of clearance there, too? (maybe a ghetto solution, for a C3 though)....

Bubba Ghetto for sure. Unless you used bailing wire as a safety wire through the latch!

I will find out on june 10th . I am having a rpm air gap installed I have a torker 2 on there now . The air gap is around .7 inch higher and from what I have checked I have 1 1/4 inch clearance now .

OK,, good,, so by your measurements, you will still have 1/2" clearance,
