Originality / GM 3941140 List 4210 1968 Z28 Holley for the crossram
« on: August 21, 2020, 09:21:41 AM »
I been trying to find information on this 4210 holley I just bought,  and not a lot of information I can find.  I emailed Jerry Macneish a few times but I hate bugging him as I know he can be a busy person.  But so far is he had been very helpful. 

I found a 4210 holley and once I got it home, i started questioning this carb. I thought all crossram carbs were double pumpers,  and without choke on them.  This one had the right numbers from what i could find with the 3941140 and List being 4210. Not so happy with the date code. It's dated 932  as I been told its a service carb, but still a 4210.

Before I got it home I sent pictures to a few friends and they all thought that some added the vacuum secondary  to it. As Jerry said that was made before the double pumpers came out.  Now I did not ask him about the choke that is on it.  And I would like to know what are the correct metering blocks for it.

I found one guy say his blocks on his 4210 is front-4743 and back is 5806.

The one I just picked up is front- 5271 and back-5806 loke the other one I seen online.   Now I would love to find a 68 inake, and the twin for this one, but i know it will be out of my reach. 

But I would love to have information on this one. As far as i can tell, the blows and blocks are the ones that came with this factory,  but I'm not a 100% sure.
Thank you for any info. 

General Discussion / Headers for a 68Z with power steering

I know this has been asked here before,  but I keep seeing names and not finding any information on them so I thought i would re ask, and see if there is any new information out there.   I asked on Facebook and people try to tell me the Z28 did not have power steering.   So here I am.

I am looking for a set of repop headers for the 68Z. I would like a set to be like the factory original (without the original price.. lol)   but who is still making the repop headers? Will they work with factory power steering?
