Just got word today that my Edelbrock Performer RPM Air-Gap manifold for my 455 was shipped out today. Should have it by the end of the week. I will post some more pics of it if anyone is interested.

 

I would like to see pictures, before and after the install would be nice.

 

You bought a cam from me didn't you? If it's the one I'm thinking of that manifold will be a nice compliment to it.

Keep us posted.

 

Yes, we did the 232/244. I have been waiting for this manifold to come out for a while now. I think they should work together nicely.

 

looking faward to this thread

 

Very curious about stock hood clearance with this manifold.

 

are 65 known for low hood clearance compaired to 68 9 or 7's?

 

Did you say pictures? Send them as soon as you can.

 

If you still have the combo you told me you were shooting for, that motor will be a beast.

Thanks

 

I will get some pictures posted as soon as it gets here. Might be a little while for installed pics. Machine shop still has my block.

 

And what would this combo be to get mark so hot ???

 

I have been waiting for that manifold to come out as well to go with my 455 that the machine shop just finished for my 48 Olds. I'll be watching this thread

 

is very tall and no spread bore , i would like a rpm for the 455 no air gap .

 

Please, please , please post pics! I'm trying to work it out on my end to fund this new intake and carb combo. I have a special request....please take a close up pic of the intake port with a gasket lined up to it so I can get an idea of how large the ports are compared to the gaskets. My heads match exactly to a fel pro 1356. The ports on my Torker are close to the 1356, but the intake was cut too far at the machine shop to compensate for the block and head work. The Performer that I have installed temporary to keep the car going has small ports compared to the 1356 gasket.

 

I will make sure to post pictures for you as soon as it is in. The gasket I am using is a mg 404. Not sure on how it compares to the others.

 

Nothing too special with my setup.
72 455 .030 over
Keith Black d cup pistons
Ga heads with Ferrea 2.075/1.710 valves, bowls blended
Erson 232/244 @ .050. Lift is .568
Performer RPM Air-Gap
C&S 900 CFM Aerosol Billet Holley DP
HEI Ignition
Hooker Headers

Engine is going in a 65 F-85 with TH400 and 3.73 gears. Just a little street car.

 

I put that same cam in my buddys 455 Olds powered T/A. He goes to alot of shows, people come from 100 yards away to ask what's in it. It runs well, let's just put it like that.
His is stock Edelbrock headed, Performer intake, 870 Holley, 3.90 gears.

I'm pretty sure 65W30 will be happy with it. Needs to be degreed and have 10.0:1 though.

 

Did some math the other day with the machining that has been done and I am sitting right at 10.0:1 so that is good to hear.

 

Thank you sir.

 

Hmmm ,now that i have the intake manifold out waiting for my stuff maybe i should order one of those,i think it should run good with my combo.

 

Sounds like perfect timing.

 

Manifold came in earlier than expected!!

 

Would definatly benefit from port matching!

I once port matched a BB oval port Torker with files and WD-40, as I got it on a Fri. and wanted it on, NOW!!!

 

As its going in a 65. Be interesting to see how it all fits.

 

You and me both

 

Thank you for the pics! If those gaskets are close to the Fel-Pro, then those ports are larger than my Performer. Did you order that straight from Edelbrock?

 

I ordered it from Summit. Had to wait a couple weeks

It would be perfect for your combo, just make sure you still cut the center divider.

 

guy gets a new intake and mark wants him to cut it up your like that little green guy on flintstone's mr kazoo . realy what or why ? and dont you think if that is or was needed edlbrock would have done that? The pp intake has the center cut? Is there a old school formula on doing this
i have read on some intake's like pontiac that it can hurt if done ??? I got a artical were mondello put a turtle in a intake tested back to back and was worse than the no turtle ? Thanks

 

Why do you think that happened?

It all has to do with plenum volume and balance. If Panos had a 950 on his 455 then I'd say leave it alone. But he doesn't, he has an 830 and a decent size cam so imo he could use the extra plenum volume and balance, simple as that.

And for the record Edelbrock tries to do thing that help performance, but sometimes casting limitations put a hold on that. Why are some notched and others aren't? Any idea?

 

So a notch cut, full cut or ? I know from pontiac intake stuff they cut the back half of the intake to work with the big q jet . Does it work with a square bore as well ? The mondello test was a king demon large flange carb. The test was a old car craft if i remember right had a mustang on the cover ,picked it up used said it was a bigolds intake shoot out ended up being two intake test edelbrock vs mondello single plane .

 

Funny that notch being brought up!
Nephew has a 495 CI stroker, Edelbrock ported head, 11 to 1, roller cammed, 3000 stall 400, 3:55 gear '69 Cutlass street car he shifts @ 5200, with a Torquer, and wonders if it'll work for him!
I suggested the full notch, as his cam is around 295 duration, .585 lift, but couldn't remember the reason I knew this!
I guess some of the reading I've done sticks in crevises of the brain!?!?!?!

 

This is what Mark did with my performer that i have on it right now ,and is working great,10,85 compression, cam (roller),238-246 at @0.50 with 592 lift.

 

the torquer is a open plenum intake.http://www.google.com/imgres?q=rotax...0&tx=120&ty=91 sorta like a two stroke boost bottle set up Is this what were shooting for on the notch to help feed left ad right on the dual plain intake pontiac guys have been cutting the back half of the intake leaving the primary and saving more throttle response than just cutting the hole thing .

 

Quick shot of Air Gap manifold sitting on almost finished engine.

 

looking Good!

 

How is the hood clearance with your air gap? How much taller is the air gap than your stock manifold?

 

You know this thread is over a year old. 65W30 has not posted a little over a year.
I also wonder how everything came out?
