Split Dominator Carbs on Dual Quad Intake??

[ZZZeee]

I want to run E85 carbs on my Edel. RPM Airgap dual quad intake but I'm having trouble locating small square bore carbs for reasonable cost. "Badged" E85 carbs are very pricey. I can convert them myself if it's a "relatively" straightforward/foolproof procedure.

 

My preference is dual 390 CFM square bore but I'm open to twin deuces or split Dominators with adapters. I'd REALLY like something easily tunable without tearing them down. Total CFM ~700-900(absolute max).

 

Engine is 350 SBC ~400HP N/A plus ~70 shot of nitrous, RPM range ~1500-6500.

 

Goal is best dual E85 carbs for the buck.
