OEM Carb for a 69 RR 383/ 727

[STAUBY38]

When I bought my car it had an aftermarket carb on it but had the original motor and intake. My question is, What Carb did it come with new from the factory? I am hearing it was possibly a Carter AVS either a 4682 SA or a 4615 SA Can anyone confirm? The car is an original AC car. Looking to go back to original....

Thanks !
CJ

Did the original set up have a carb spacer to raise the carb off the manifold?

I’m not sure they did. You’ll need ones with today’s gas that boils in mere minutes. Most rebuild kits seem to come with a spacer.

Thank you !

I have never run a spacer and never had any fuel boiling or vapor lock issues.

Most 383 road runners came with AVS4426S with 630 cfm 4speed and AVS 4428S and 4429S for 440 and agree with torredcuda

I have never run a spacer and never had any fuel boiling or vapor lock issues.

Plus if you have an air grabber, this is not an option due to clearance issues.
