EDELBROCK Performer 2101 VS. 2701

[LEEJANDZ]

I know there have been a lot of posts on the EDELBROCK Performer 2101 but I havent seen anything on the Performer EPS 2701. Does anyone have any experience with the EPS???

I currently have a 79 L-82 with the stock EGR manifold, and I want to go with a better intake. I am planning on removing all the smog equipment so I wont need an EGR equipped manifold. I was looking at both new & used intakes and now I have a problem.

Should I consider the EPS 2701???
Or should I go with a 2101???

With the relative small $$$ difference between new & used, should I look at used 2101's???

Or is there a mystery option #3 that I havent thought about.



I want a street VETTE with a balanced 350HP/350TQ (for now)

Jason:
If your 1979 passenger vehicle is registered in Orange County CA ... I understand it is regulated by some of the most restrictive smog laws in the nation ... laws & policies that routinely cause car enthusiasts big headaches when their cars fail smog inspections because emissions equipment has either been removed or modified. When it comes to changing carbs, intakes, cams, smog pumps, exhausts etc ... I suggest you first research what is both practical and permitted in your jurisdiction. However, if you have a buddy down at the inspection garage ...

Jason - will the smog nazis allow you to eliminate EGR in CA.? For one thing,an adapter plate would be required to use a quadrajet with the 2701. Also,I would be concerned with hood clearance with a stock hood with the 2701. You can call the Edelbrock hotline,they are very helpfull with info.

The car is currently smogged and registered here in ORANGE COUNTY CA --- land of strick CARB requirements and the only 305 CID in CORVETTE history. I wont have to worry about the smog again until OCT 2005, So by then if the laws are still as strick, I will have the car re-titled in OREGON.

Thanks for the tip. Is the 2101 a direct bolt on without any adapters or hood clearence problems???

Jason - So far so good with hood clearance. Others on here say they have used the 2101 with stock carb and air cleaner. This is my goal,also. I will tell you one thing its VERY close,looking at my preliminary measurements. I want a minimum of 1/2" clearance between my air cleaner and hood. I am going to use a thinner gasket/insulator (btween carb and manifold) than the 1/4" factory type.I have several types I am going to to try for a little extra clearance. I 'll keep you informed on what I come up with. I would make sure your motor mounts are in good condition,so the engine does not lift to excessively during acceleration.
Quadrajet mounts to a 2101,no problem at all there.


See ya.........Dave

I have an aftermarket chrome air cleaner, and would like to keep that look, do you think I will have fitment issues???

 

[Dave L.]

Jason - I think you'll be Ok. If you get a chance,measure the heighth of your air cleaner and I'll compare to my stock one. If I remember correctly,the 2101 sits(where the carb mounts) about 1.5" rear and .75" front higher than your stock manifold. I can verify that for sure.

Just so we are measuring the same thing... From the base of the air cleaner lid to the top of the wingnut???

Intake Manifold, GM Cast Iron c/n 3973460 F = 2.69” R = 4.38”
No that's not a misprint ... I measured it several times same way as edelbrock does ... my OE is tall in rear & short in front ... interpret that as this OE intake has a much steeper angle on carb pad than most popular replacement intakes. That angle has a great deal to do with how LITTLE clearance one may have between FRONT of lid and hood when fitting an aftermarket intake.

Intake Manifold, Weiand Al p/n 8004 F = 3.50” R = 4.00”

Intake Manifold, Edelbrock Al p/n 2101 F = 3.50” R = 4.60"

The cast iron one is OEM from my 71 L48 w/Qjet. Go to edelbrock site for good graphical explanation as to just how those measurements are made ... much better than I can write about it. Weiand 8004 is functional equivalent of E 2101 ... perhaps a bit better ... cheaper too. All 3 fit Qjet ... Both W & E also have holley pattern.

Wad up some aluminum foil & lay atop the lid ... close the hood & compress the foil. Open and measure foil thickness. That'll give you a good idea how much clearance you have now. Do it at both front & rear of lid.

Thanks for the info. Just out of curiosity what intake manifold are you using???

If you say the WEIAND 8004 is better than the EDELBROCK, why dont more people use it. Do you have any flow comparisons or dynos comparing the 2???

(just when I thought I had what I want another option appears, I love this list!!!)

From what Jack says,using the Edelbrock will actually tilt the front of the air cleaner slightly lower than the Weind,which would give you a little more clearance at the front of the air cleaner where its most critical.

My quote from earlier “perhaps a bit better” ... perhaps ... a bit. Look at advertised specs W = idle-6K, E= idle-5.5K. Have heard other anecdotal evidence to support. I’ve also looked at both ... the Weiand ports look a bit better. More people know the Edelbrock name because Edelbrock’s strong marketing on too many boy racer TV shows/commercials ... Weiand rarely. Human nature ... people buy what they're familiar with ... even if they know little about it. When you start getting into very tall single plane intakes as on drag & some circle track classes ... then you find Weiand Team G intakes becoming more popular. I’m running stock air box, stock gasket, tuned Qjet, stock carb spacer, stock L48 low hood ... all factory 1971 but with W 8004 intake on 388 sbc ... it clears just fine on my 71. My ES poly mounts set motor in stock position ... but they are firm & do not let motor twist as much as a set of worn out rubber mounts. Either the 8004 or 2101 will flow more than I am likely to ever need ... whatever benefit one MAY have over the other is a hair I'll never need to split. I got the weiand because they're cheaper new & a lot cheaper used. I'd have used a 2101 just as quickly but didn't see any almost new 2101's for $50. I do know dyno tests on E 2101 ... around here (circle track regs) all late model stock & supertrucks MUST run an unmolested 2101 ... and they MUST use a 500 cfm TWO barrel holley carb sitting on an adapter plate. We have a motor dyno in the race shop ... those same 355 sbc motors make about 370 hp ... w/ a TWO barrel on a stock 2101. If I had to hazard a guess there's probably a similar offy (Offenhauser) intake that's perhaps a bit better than either 8004 or 2101.

From what Jack says,using the Edelbrock will actually tilt the front of the air cleaner slightly lower than the Weind,which would give you a little more clearance at the front of the air cleaner where its most critical. Dave

Dave's probably right. But angle ain't everything. I’m NO trigonometrologist (but I push the “scrabble” envelope) ... both W 8004 & E 2101 are taller overall than MY stock intake ... that too is important ... and part of the “equation.” Hence ... use the tin foil ... and also measure existing intake per Edelbrock/industry method ... lay long straight-edge across carb pad ... drop a line from s-e to intake’s front & rear lifter valley gasket surfaces ... those lines' lengths are the front & rear measurements.

What about the WEIAND 8024??? Any thoughts???

Jason:
No first hand experience ... 8024 appears to be essentially same as 8004 ... except for one HUGE difference ... 8024 appears to be for Vortec heads. C3 vettes did not come with Vortec heads. Some guys put Vortec heads on ... with varying degrees of success.
