Hi guys,

I need to replace my 4 barrel carb, Holley 6R3452B. I bought the car with this carb mounted on.

The chokes are rusted and the electric control is not working properly.

I don't have any info on this carb. Does someone have some?

Is it still available?

Sorry I made a mistake, Carb ref is 6r3752b

I've never seen a list number like that... are you sure that's really the list? It does not show up as a good number...

If it's not the original carb, maybe you should look for a nice upgrade.

The number is on the top front of the choke housing, right side looking at it.

That's a Holley part number.... not a "LIST" number. Unless the air horn has been machined off, the LIST number should be visible on the air horn.

Thanks guys for the info.

I confirm that the carb is a Holley one. I will check for the correct P/N on the air horn.

I want to get rid of the electrical chokes. I would like to use a 100% mechanical 4 barrel Holley 750cfm carb.

Can anyone recommand a carb for a 427 chevy bb?

I run a mechanical trans.
Street use. I need a quick reaction when shifting the gears down double clutching. I live in Europe in a area with a lot of twisty roads and mountains.

I suggest you consider a Barry Grant Speed Demon 750 mechanical secondary without choke, BG part number 1402010. I can send you a complete installation instruction article with photos and part numbers if you'd like.
