Recently decided to go with a 600 cfm edelbrock performer carb, with the performer mainfold as well. I was wondering if anyone knows if a 14 in open air filter will clear the hood of my 1980 L-48. I believe these are the 3 inch deep ones if I'm not mistaken. Any info will help. Thanks

I don't know the answer, but the Edelbrock Peformer intake is supposed to fit with the stock carburetor under a Corvette hood. The Edelbrock carb is no taller or maybe even a bit lower than the Quadrajet. The air cleaner you want may fit just fine, but if not, there are drop down air cleaner bases available so you can still use the size air filter you want.

will it clear the distributor? don't think it will on my 79.

I looked at mine and measured it, and it doesn't look a 14" air cleaner will clear the distributor. All I can suggest is try a smaller diameter or shape. Holley makes a two element air cleaner/filter assembly where it's very low profile, and the filters fit on each side of the carburetor. Striking looking, but pricey.

As far as I know, the only intake manifold that Edelbrock states will fit under the stock Corvette hood is their Performer model. Their catalog says their other intakes won't fit. You can always contact Edelbrock and ask their advice for sure (<www.edelbrock.com>). Tell them exactly what you want to do and not do with your engine and they'll give you good advice.

I have that setup. The nut on the air cleaner leaves an indent in my hood insulation...

My '81 has a performer manifold/w a Q-jet, 14" K-N filter. I had to get a dropped base from a Edelbrock filter and carefully grind away about a 1/4" of material around the base where it meets the throat of the carb to get enough hood clearance. And you may have the grind down the tips of the wing nut.The back edge of the filter base does touch the distributor, but it will fit and not pose a problem. You kind of have to "jockey" it in place. Hope this helps.

Everyone is asking about clearance and its a simple thing to check. Most of manifold manufacturers give a front and rear height measurement.

To determine the height of your stock intake unbolt the carb and place a flat straight edge across the carb mounting surface that will extend to the front of the engine block to the rear of the engine block. Then mearsure from the bottom of the intake/top of the intake valley of the block up to the straight edge. Do this on the front and rear to get your measurements and then take those and search for an intake of the same height.

If your wondering how much you can give and take to the hood height. Go purchase some soft molding clay and place two inch round ball of clay on the front of your air cleaner and another on the rear and shut the hood. Pop the hood and measure the thinkness of the squashed clay. You may need to use more or less clay depending on what you think is needed to meet the hood.

I've measured mine and its very low and it matched the exaxt front and rear heights of the weiand 7547 intake. This intake is a very low dual plane intake. Measures 3.09" on the front and 4.06" on the rear. Since its such a low single plane it shouldn't hurt perforance down low too bad. If you can find it, because its now obsolete. Weiand 7525 intake is a single plane intake also fits under the corvette hood upto 1982. It measures 3.50" front, and 4.50" in the rear. Use the 7460 or 7461 Plenum divder with intake to get better low rpm vacuum. It also has an EGR provision.

Hope this info helps.
