460 baseline 850 carb settings

« **on:** September 10, 2012, 09:01:56 PM »

Here's my combo
460 Dove A high comp.
Mild cam
Iron CJ intake
Logs
Mech fuel pump
Getting ready to switch up to 850dbl pumper. Looking for baseline jetting and whether I should run power valve on secondary. Note, choke horn removed. Was also thinking of trying reusable bowl/metering plate gaskets. Anyone have any problems with those gaskets?

Stock jetting and go from there

The stock jets on a list #4781 850DP could be 80 pri/sec or 80 pri, 78 sec depending on what the number is following the list number.

Set it up with stock jetting, run the power valve (probably a 3.5, but you should see how much vacuum your engine is pulling), and start with your idle screws at 1 1/2 turns out.

I don't have a problem with the non-stick gaskets but i'm one that still recommends using Holley parts on Holley carbs.

Cool, thanks. Carb has been modified and wasn't sure how close stock jetting is. I wanted to use reusable gaskets until I got it dialed in. I have a trick kit full of gaskets, jets, squirter's etc from my bracket racer days. Raced a BBC Nova and still learning as much as possible on the vastly superior BBF.
