Thanks for the explanation JohnZ about the carburetors!

So the distributors were not installed with the engine assembly when shipped as they were shipped naked? Was the distributor that was tested with the engine reunited at the car assembly plant? When were those chisel marks done at the final assembly of the car?

As you can see in the photo I posted, the engine as-shipped included the distributor, but very little else in terms of bolt-on parts; anything you don't see in the photo was installed at the car assembly plants.

This is the reply I just recv'd about the carb, no pic was supplied when I asked. Actually I tested the reserve ($500.00), yeah risky I know, and it hasn't been met yet. Not sure if I should trust it.


This is it's original 4053 Base plate. It has 3 vacuum sources, an angled 1/8" port directly under the primary float bowl which was used for the choke pull-off and/or smog system vacuum source, a 3/16" vacuum port on the right front corner for the vacuum advance, and a stepped 3/8" port on the right rear corner for the PCV hose. The Fast Idle Lever is missing, the Factory Screw is intact. Found one here on ebay for 10 bucks.

If I was to look for those parts would they be hard to find? I have 5 sheets a friend gave me in 1975 from a HOLLEY CARBURETION VARIABLE SPECIFICATIONS AND PARTS counter book , page 81 and 82 showing the 4053 carb numbers, page 240 that has the exploded view of the 4150 TYPICAL VIEW ILLUSTRATION NO 34-1, page 241, 243 with part names and index numbers.

Fast idle cam is (136)41R-539 and the fast idle lever is (6)4R-852. The missing screw is not found. Just wondering if if I should waste my time on this or let it go.

I have a 954 and been looking almost a year for a late January/ February.  Tough to find and not paying 1500!

Al at Chicago Corvette will have those parts, but they are probably expensive. I was reading the sellers reply, he doesnt have a clue what he is talking about, they dont use a screw for the fast idle, the missing lever has a tang that is bent/adjusted to set the fast idle on the Fast Idle cam steps. They are not $10. You should insist he post a picture of the drivers side of the carb, as well as a under neath shot, its no trouble to add pictures, if he doesnt want to comply dont bid. I have seen many DZ carbs with the later issue reinforced baseplate, (originals were prone to breaking on the LR corner) plus the wrong accelerator pump housing and lever, originals use clutch screws., plus ask him the secondary metering block number, it should be 4519

Those are the "correct missing choke parts"
Accelerator Pump housing looks like it has clutch screws, and the baseplate is the original unreinforced line installed. The choke pull off has been changed at 1 time as it appears to be a straight nipple. Original 4053 has a small bend in the nipple where the vacumn line pushed on. No Big Deal.

I'll keep you posted. Not sure how much I should bid on it though. What do you guys think? I took it to $500.00 and didin't reach the reserve. I think someone else went fishing to see what I bid and then stopped when they reached my bid and hasn't gone any further. I hate it when that happens.

That's a PITA. Hopefully another one will show up soon.

I've been looking for 13 years and have only seen maybe 3 I could bid on. All the ones that are on ebay are way over priced and restored on top of that. I'm just looking for a good core to rebuild. Somebody has to be sitting on these carbs. Or all the carbs made have been destroyed.

Yeah I know. I'm currently using a service replacement now, dated 0811. I also have a 4777 650 dbl pumper I set up that works quite well if I want to fool around. I like that carb, but it makes my gas gauge needle move too fast towards empty. Works really good with the -140 cam too. I still want to find an OEM though.
