edelbrock performer rpm intake vs victor intake

[fordracing65]

What is the intake of choice for an FE 482, the Edelbrock RPM or the Victor, and what are the differences in performance between these 2 intakes for street/strip driving, going in a Kirkham, I heard there might be hood clearance with the Victor, thanks for any help.

I may have a ported Blue Thunder available.

What is your redline and typical rpm power range? For mostly street driving with a 5500 redline, the dual plane is the way to go.

Wow, where do you start on this one? This is a real apples to kiwi fruit comparison. Single plane vs dual plane. Assuming you're talking carb, a single plane manifold is more suited to higher rpm application for reasons too numerous to list. That being said, a Cobra is a pretty light vehicle so a single plane manifold might not be as detrimental as it would be in a heavier street driven vehicle. A street driven Galaxie for example, would be a dog with a single plane intake.
Now fuel injection is a whole different fruit, and a single plane would work just fine for a port injected application.

Carb motor and a 6200 rpm redline is what im looking for.

[Bitten Bob]

With such specs, for street + only occasional track, it's a no-brain choice... Go dual plane ! More torque at low and mid RPM range...

[mreid]

I have a dual plane (performer RPM air gap) on my 427w in my Kirkham. This engine has a 5600 redline and more power than I know what to do with. I wouldn't have it any other way!

I ran a victor jr. on the 392w in my Factory Five coupe. Both engines had a 750 Holley carb and the same Ford Z heads. Hands down the dual plane wins for my uses (spirited street driving).

All dual plane vs single plane arguments go out the door when you're talking about 482 cubes. If this was a 352 or a 390, my answer would be different, but an engine approaching 500 cubes can get away with non-typical items. The same idea applies to small blocks. A 351W would be a little fussy with a Victor Jr or Super Victor intake, but a 427/445/460W would be right at home with one. They need the extra plenum volume and can handle the demands that a short runner places on a smaller engine.

If you have the room under the hood, my vote is the Victor FE. You can still have a very nice streetable engine with a single plane intake...I promise.... Let the cam put the peak where you want it, run plenty of advance in the cam timing, and let her eat.

We all know Blykins knows his s h i t. Thanks for the info.

A few years back, there was a thread where a member ran an FE on the dyno with a single plane, swapped to a dual plane, and ran a like for like comparison. Based on a memory I do not trust, I think it might have been a 390, but I'm not sure. I believe the single plane lost very little on the low end and gained quite a bit on the top. You might do some searches.

I would say if any engine would break with the conventional knowledge on single verses dual plane intakes, it would be the FE. It is a very wide intake, given the head design. I expect the runners are long enough to make a difference, especially when you compare it to a SB.

I vote with Blykins. It is usually unwise to bet against him.

My mind went in the same direction as blykins. Anyhow the book is called, The Great FE Intake Comparo by Jay Brown.

I agree with Blykins 100%, I have a Victor Jr. and it produces plenty of torque at all rpms with a 1600CFM throttle body. The last thing you need in a Cobra is more low end torque, especially with big CID FE. Go for the Victor you won't be sorry, I even had a 1300 Dominator on it that worked well too.

I have run single and dual plane manifolds with both dual fours and single fours on a number of FE's and I always liked the single plane manifolds the best.

Like is said before, #3170 I agree with your opinion on cobras over all others, the only problem with the Victor is getting it to fit under the hood, I will be using a 950 carb.

[Danr55]

I have a performer for sale if you're interested. Took it off when I fell into a C7AE 9425F all polished and looking pretty.

The Kirkham engine mounts are little taller than original, you might be able to gain something there (make your own) you can also mill the carb mounting flange and gain some there. If you have a hood scoop you can use some of that real estate to fit a custom air cleaner. I have a hood scoop and am partially into that area with my air cleaner, but I have a 1" Wilson spacer on the manifold along with their throttle body, I am pretty sure the total height is greater than a Holley carb. Check out their engine mounts they are a great design just too tall. I'll measure the distance between my china wall and the edge of the body that would be flush with the hood and send it to you tonight.

It is 13" from the FE china wall to the cowl top at the hood center line, my manifold, spacer, throttle body and air cleaner stack are just below the bottom surface of the hood at the rear.

Thank you so much #3170, when I get my car done lets race. lol

[blykins]

Maybe the Kirkham boys will cut the motor mounts down for you a bit....I don't know how bad it would mess with the trans mount and pinion angle though. Might wanna ask Tom/David.

I can mill quite a bit off the Victor intake for you, so that's no problem. The Victor requires quite a bit of work to be really functional on an FE anyway, so one extra step isn't gonna kill anyone...

Just as long as it does'nt get so crazy I loose performance and run into unforseen problems down the road beacause of so much tinkering.

[blykins]

You don't have anything to worry about, but if the Kirkhams can work some voodoo on their end, it will be easier for everyone.
