5.7 Hemi Dual quad w/600 carbs....initial carb set up

Came across this 5.7 Hemi dual quad intake and decided to try it out with a couple 600 AFBs/Edelbrocks.

They are the electric choke versions, supposed to be calibrated lean per E's site...All the choke stuff will be gone from the front carb and the vacuum holes drilled/tapped/plugged.

Been considering going with Edelbrock's "4 percent rich" calibration for the manual choke carbs as a starting point for jets and metering rods, just to make sure I'm starting with something halfway safe.

Bad idea? Not sure if I'm overthinking it...normally I'd start with stock jetting but when the mfr admits it's deliberately lean, I'm tempted to try to correct it before I even get started.

Anyone run a similar dual quad setup...what kind of headaches to expect? I can't imagine it being too far off from a 340 or 360....

Think I can get away with 1:1 linkage on a mostly stock 5.7, or will it need to be progressive linkage? It might get a stock 6.1 cam at the most, other than that no mods.

Sorry for the lousy cell phone
picture, it was the best I could do at the time...

Looks sweet. I would set it up similar to a 340 and go from there...

Zippy, I'd try it as is... just do a couple of short
run up's then check a couple of plugs.... looks cool

Good point Mike, there's really no break in to worry about so if it's hideously lean I can just shut it off and fix it.

I'm probably overthinking it, but haven't worked with AFBs in a LONG time and never messed with multiple carbs....

which 600's are they exactly? FWIW on my 360 single 4bbl engine I needed to lean the 1406 carb out about 1 step on the primary and 2 or 3 jet sizes down on the secondary.

They're 1406's, and I've stripped all the electric choke stuff off the front carb.
