Greetings . . .
I would think that a pair of BXOV-2 carbs would run great on a 302.
The stock Holly 94 is similar to the Stromberg 48 - in the 170-180 CFM range.
The BOXV-2 was standard equipment on small displacement sixes (Chevy and Dodge) during varying years from the early 30's to the mid 40's (sourcing moved about between Carter and Stromberg
CarbShop-Applications ). I've never seen a CFM rating - but given the engines it was fitted to - it is likely to be in the 120-130 CFM range. With two of them you will have perhaps 50% more carb then stock.
So you won't be starving . . .
regards,
