E4ME Electronic quadrajet question.

Hello all, I am in search for replacing my car's stock quadrajet with a brand new/remanufactured unit because of age and vacuum leaks all over the body. I have recently modified my lg4 and am a bit stumped as to what to look for... the engine is breathing much easier (heads and cam have been upgraded) and i'm not sure if a stock re-manufactured E4ME quadrajet will suit the AFR requirements at wide open throttle. As of now, it sputters when the secondaries open due to fuel starvation. Heads are world S/R torquer 305's, 1.94'' intake valves and 1.5'' exhaust. 58cc combustion chambers and 170cc intake ports.

Cam specs:

Duration at 050 inch Lift: 210 int./216 exh.
Advertised Duration: 270 int./276 exh.
Valve Lift with Factory Rocker Arm Ratio: 0.440 int./0.454 exh.
Lobe Separation (degrees): 114

If there are any options out there for modifying the new q jet, or getting one from someone that modifies/tunes these (if needed), please let me know!

Best regards,
Zack.
