Basics:
400 bored .30
KB Hypereutetic 9.5 to 1
.525 Lift Cam 275/287 Duration 110 Centerline 231/237 at .050
440Source Stealth Heads
Static compression around 10.05 to 1
Mopar Performance 1.5 ratio roller rockers
Edelbrock Performer RPM
Holley 750 Double Pumper (3310)

What jets should I use in this carb to maybe get it close to being correct? What jets come in these carbs out of the box?

You might find that the carb works best right out of the box, try that first.

A 3310 isn't a double pumper.
Pardon me but my karma just ran over your dogma.

I agree with  John....start with the stock jetting. I think it's 72/80 with a 6.5 PV but it's been years since i fooled around with a vac secondary carb so don't quote me on those jet sizes.  :P

Yes, the 3310 is a vac secondary carb....no accelerator pump or metering block on the secondaries.  ;)
