Holley 4160 Adjustable Float Carburetors 0-8007
Carburetor, Model 4160, 390 cfm, 4-Barrel, Electric Choke, Single Inlet, Dichromate

Was: Main Jet 54, Power Valve 9.5 - cylinders 1&2 complete carbon

Now: Main Jet 52, Power Valve 8.5 - Cylinder 1 dark brown from video.

When I had the 9.5 in it, the bogging was gone and I could easily spin the tires. Now there's bogging and hard to spin the tires off the line. Of course, the tires squak when going from 1st to 2nd (200R4) at the higher RPMs. I've got reasonably fat tires in the back and the original 3.08:1 differential. My goal is not to spin tires, but it's an indication of how well it runs off the line. Love to try taking it to the drag strip, never done that before.

Lots of discussion on the other thread about timing. Distributor needs to be trimmed, but gotta fix this.

Thanks!
Mark
