So i'm pretty sure this carb is bad & am looking to swap it with a better carb , does it have to be governed ? Are there better carbs that boost HP?



Any info would help thamx Dan

 

To be goverened, no as long as the operator does not overspeed it. I was always a
Holley guy, BUT weather here is like a yo yo. Those gov. Holleys don't like the damp
in the 30's degree weather carb icing black smoke the govornor all iced up. Then the
leaking accelorator pump due to this crap gas. So for around $250 for a new manual
choke Eddelbrock, what a difference no more icing or leaking. Would have kept the
holley but I can't find a good kit all these kits are junk nowadays....

 

You can install a non governed carb on the engine but I highly recommend you purchase some type of rev limiter (MSD, ect) to prevent the engine from over revving (3900 rpm max).
We had a couple of 391 powered trucks with a bad governors, I can personally tell you if over revved much it can and possibly will crack a piston, break ring lands out of pistons, crack cylinder walls, jerk the end out of a rod, break the crank shaft (be there,had them all happen).

 

Hi I'm new at this ) so enclosed are the carb # off the carb as I'm trying to verify it is a 4150g I'll try to show a pic of the entire carb also any info is appreciated

 

Yes it's a governed Holley for a Ford truck.
Use the List # 7350-1 when ordering parts or rebuild kits.

 

Here's the carb I used;

I would not expect any HP gains. Holley lost my following with the introduction of plastic. The manual choke cable connector can break off. The plastic rod for the choke plate will blow out if the engine back fires with the choke closed.
Old school governed Holley or Eddelbrock.

 

Agree 1000%/\ /\
