Holley 0 80458SA Polished Universal Carburetor Review

Amazing carburetor, perfect out of the box does not come with a 2-in-1 fuel rail You must order one if you don't have one, it's an 8" 21 /32 seconds center to center

Looks like a good carburettor. I bought an electric control valve for my brake booster vacuum pump a few months ago. I just installed it on Saturday. He shut off the pump at 10 inches of mercury. I tried to adjust it but I couldn't turn the adjustment screw. 😩

The floats only needed a small adjustment, but they are installed immediately and work perfectly. Update: The carburetor suddenly started having problems. I found two gaskets on the power valve, loose bolts through the entire carburetor. The internal casting of the metering block is sloppy and rough at best. I'm really disappointed in Holley as apparently they too have lost product quality control like so many others.
