Hemi carb jetting

[dart6]

Is anyone running twin Holley 4235 and 4236 770cfm secondary carbs on their 426?
If so do you care to share your jetting please
Stock crate motor with the marine manifold

As I recall, back when I ran my Factory 68 Hemi Dart,
The jetting that came in the factory 770 Holleys
was pretty close at Sea Level and a good start.

Is it a dedicated race car or a street car that runs thru mufflers
and real Air Cleaners?

It's a street car with mufflers and air cleaners. The main jets are #74. It runs rich and fouls the plugs

Check you power valves as the jetting sound about right.

The cross ram intakes do not have the best street manners.

The power valves are blanks
