Help "tune" my supercharged 360 1972 Dart, please!!

Bigger squirters and maybe a 50cc pump like yellowdart says would be a good first step.

What do your plugs look like? 74's are what I run in high altitude hear on my mild 360. I would up those jets two sizes at a time while keeping the stagger the same. Also, I really think you should be running a double pumper on a blower.

I have a zero experience with SC cars but I think dedicated SC carbs have a different vaccum reference for the power valve too. Let me check on this...

I might carefully up the intial timing while keeping the total where it's at for now too. Detonation on SC car is deadly to pistons.
