ZL1 carburetor

[JoeC]

Did the original ZL1 Camaro Holley use the choke?

[Chevy454]

I don't believe so. No provision for a choke.

[Jeff Murphy]

Yep. I think you are both right.

[Ed Cunneen]

No Choke. Also, ZL-1's don't use a temperature controlled heat riser on the exhaust. There is no provision in the aluminum head to transfer the exhaust to the other side through the intake manifold.
Of course you will probably be using headers anyway.

I see that Ed has answered my question.

Thanks for your input Ed.

re : Ed C'c rebuttle... Hi, I sorta find it hard to believe that the ZL1 car's choke plates were not present on the orig 4346's or 4296's. Can you please explain your thoughts on this? I ask as I have an NOS one of these dated that has the choke present. Ive had many 4295's that obviously would follow this thinking; but I am all ears to your knowledge...

I agree with Kevin S. on this one. The "problem" if you want to call it that, is the depletion of rare date coded parts for the authentic cars that "deserve" them. Now anybody who pays the money gets to do whatever he/she wants to do (Turn that NOS ZL1 block into a coffee table stand, whatever), of course. But when folks start buying date coded correct stuff for a clone, it just seems like a waste. I mean you may have a carb date coded to the car, but the car's supposed to have a 307 and a powerglide, so who cares? And since you're building a clone, why not use the best parts that work and look right, rather than the "original" parts. I've heard of guys using real COPO rearends in their clones. WHY? So the one guy in 100 who crawls under your car and reads the codes gets a surprise?

The only upside is, when some of these guys go nuts building their clone with correct parts, the clone can later be purchased as an excellent donor for a "real" project car.

This isn't a bash on clones - I've got a '66 Shelby clone in my possesion as I type this. But I'm not out chasing NOS tires for it or anything. I'm not even hunting down a Shelby-correct '66 t-10 4 speed. I'm putting a t-5 5-speed in it so I can have my cake and eat it too. Vintage Shelby appeal on the cheap, and reasonable cruising on the freeway with 4.11's. And nobody looking at the car as it goes down the freeway will care one way or another about my tranny.

JMO,
TOM

I need a 4346 or whatever else would be cosmetically correct (date unimportant)....Would the larger CFM 4296 be wrong to use on a hydralic cam, oval port 427....I also need a 163 Intake....Thanks, Chuck

I would think that using a date coded correct part in building a clone would be excessive if it were a part that someone could use in the restoration of a "real" car. It would be a shame to have the badly needed date coded carb on a clone while someone needing that part could not find one. This particular situation is a bit different though. How many 69 ZL-1 cars are out there that are going to be found in which the owner cant find a correct carb? Seems like the number would be few. If someone comes up with a lost ZL-1 and cant find a carb I would think Kevin H would be more than willing to part with it in that case. In a round about way by him using a correct carb on his clone he is actually preserving it so it does not end up on some teenagers hopped up 77 Monte Carlo on it's way to a junk yard. Also, by building the ZL-1 clone to drive, the real one Kevin has is thereby also being preserved as when Kevin feels the need to drive a ZL-1, the real one is safe at home with no danger of being slammed into by some idiot, while Kevin still gets to enjoy driving one that is no different except for the VIN due to the fact the clone was built correctly. Not being a fan of clone cars myself, this is a situation where I think the idea justifies itself, considering all that Kevin H. has done to preserve this hobby. Some people just want the best they can possibly have, that trait in Kevin has led to the correct restoration and preservation of many a fine Supercar, so keep up the good work Kev!

Its' my understanding that the first ZL1 came with a incorrect Carb which was later changed/updated. Subsequent cars received a Carb with a choke plate.

If I'am wrong, set me straight please.
