Ah; A Q-Jet, that's a thought & from a 305" that will work, good idea.
Hurry & get that EFI system developed & we all can throw our carbs in the dumpster.
LPG pistons are still 'dished', just not as much. You need flat top or doamed & there $600 (bummer) but necessary.
That way you have (exactly) what YOU want.
Remember; The bore, stroke & compression are the engine's "foundation"......
