The Ford Barn

demingboy · 08-03-2022, 12:15 PM

So my 1941 ford sedan has a newer 1951 mercury flathead in it. Has a chevy conversion dist. in it and am trying to run a holley 390 cfm. carb.
I have read all the information about this carb set up and they either know how to adjust carb better than me or mine is just messed up. I am thinking the latter.
So my question is that I want to install adapter and go with a 2 barrel as I think its just dumping too much fuel. Really gags it.
Looking at older 289 carb and wondering if it will run backwards alright. I think this old ford must be one of the few with carb linkage on passenger side.

I run a 390 cfm on my car and have built 2 or 3 more with the same carb. Pretty much a bolt on. Very little adjustment needed.

All of the 33-48 fords Ive owned have the linkage on the pas side . I run a holley 390 with no problem. What intake do you have ?
Yes the 2 barrel autolite will run backwards . If you have a 4 barrel intake , be careful some adapters are poorly designed and have the possibility of having the nuts come off in the plenum .

The Holley 390 is normally operated from the driver's side. I modified the linkage on my 390 to move it ti the passenger side.

cool. Thanks guys. I think I just need a rebuild on my carb. Meanwhile I disconnected the secondaries. Will checkt it out later for performance.
I have an old weiland 4 barrel intake. I think I spelled that wrong
