Performer intake and choke

[Johan]

I'm about to install a Edelbrock Performer intake, but will keep my stock Q-Jet (4MV), and just today I realized that I will have to do something with the choke. What is the most common and simple solution?
Edelbrock has a choke kit for their Q-jet clone (#1931) to go with the Performer intake, will it fit the "original" Q-jet?

Johan -

I have accomplished this same swap several times. You can use your stock choke rod and just adjust accordingly. The Edelbrock rod is also fine, you just need to recheck the measurement (top of rod even with bottom of hole).

I suggest you use 12-point fasteners, especially if you have A/C, as you need to check the bolts on occassion, and the 12-point bolts make the center ones easier. Also remember to slather some Permatex #2 or other type of sealer on the bolts to avoid oil creeping up the bolts onto your nice new intake.

I would be interested in how your hood clearance is affected and what type of air cleaner you are running. While I have done this swap on Chevelles and other Chevrolet makes, not on a Corvette. I am contemplating this same swap on my '72, and have the stock hood.

You will like this manifold swap-there is a noticeable difference.

Rick,
I don't think (I don't hope...) that hood clearance is an issue, the Performer shoud fit under a Corvette stock hood. The Performer RPM and other intakes will not, though.

But I don't understand how I can use the stock choke rod, where do I put the choke coil? :confused Do you mean that the stock coil still will fit (if i turn it 90 degrees and tilt it 45)? I did not think of that, since the area looks totaly different.

 

[RodsnRides]

Yes-the stock coil and rod will work. You just have to tweak the rod a little. I also found that I had to modify the little choke coil cover by slotting it with a Dremel tool with a cutoff wheel. This is to allow the rod to move freely-it tends to bind on a non-modified coil cover.

I assume your intake is new in box, and came with the gasket, pad and 2 allen bolts that bolt onto the intake and is made for the choke coil.
I recently acquired a digital camera. If you need me to post a couple of photos, please advise. I can e-mail them to you as well.

Ok, I thought they were made for a different type of choke. The reason I got a little confused is because I bought an intake on ebay (photo) and it has a totaly different choke arrangement. Well, that intake is sold now, (bought for $40 and sold for $140 in Sweden!!), and I will get a new in box from ebay (actualy I had a new last week, but I sold that too.).

One more thing

Almost forgot. If you are removing a stock, EGR type intake, you need to change to a choke coil from a '71 or '72 Chevrolet product. This is because choke coils made for EGR intakes are made to work in the hotter EGR environment. I assume your new Performer is #2101, the non-EGR type intake.

If you stay with the stock EGR choke coil, it will take much longer for it to "relax" and come off of choke. Hope this helps...

Okay, now that I've seen the picture, the choke set up that is currently installed on your intake is for a "hot air" choke-more common on '76-'78 or so Q-jets.

It looks like the choke coil pad you need for the so-called "divorced choke" (coil and rod) is zip-tied to it with the orange tie. Hard to tell from the side view presented. But it looks like it.

You will need to swap the piece out-remove the installed set-up and install the tied set-up (I think). Can you give me another shot of the thing that's tied to your intake? The proper coil pad will have a screw hole for a fine thread and a little bump/nipple/teat opposite that for the choke coil to set on.

[Johan]

Hm, I did not think of that. The thing is that I do not have an EGR valve, so I assume that someone has changed to an earlier type manifold (it is still cast iron, but I have not checked the casting numbers), but I have no idea what type of coil is used, I just assumed it was the stock one. Maybe they changed the coil too, maybe not. The choke seems to work fine though.

Thanks for the help!

Pleasure

Happy to help. Sounds like you have the non-EGR choke coil already, since it is apparent your intake was changed. Good.

Can you confirm you have the divorced choke type pad for your intake?

Rick

 

[Johan]

Yes, that is the plate (the same that comes with a new intake).
Since that plate is sometimes called "choke block-off plate", I just thought it should be used to totally block the hole (didn't realize you could mount anything on top of it), thats why I was even more confused.

Okay, I think you should be all set then. Woo-hoo!

Some New Zealand friends of mine recently got married in Sweden, not far from Stockholm. I don't remember the name of the town, but they gave them a flag. It was red, yellow, and grey, with metal working tools and images also in the flag. The family they stayed with are members of an international Mastiff club.

Best,

Rick

Are you SURE About Hood Clearance???

Johan, RodsNRides,

Are you sure the Performer manifold will fit under the hood? Checking Edelbrock's website, they directly say that Performer "will not fit in Corvette". The only manifold that they say will fit without hood modification is the single plane Torker.

Anyway, I'd be real interested in your result.

Thanks

hey Ernie, you can fit alot of things under a corvette hood with a drop base filter. i've got a rpm air gap under mine

Johan, RodsNRides,

Where do you see that? They say that Performer Air-Gap, RPM Air-Gap and Performer RPM does not fit under a Corvette hood, but they say nothing about the "basic" Performer what I can find.

Well, I will find out the hard way...
