Oh wait now...ok, sounds like you're talking money now, and 750 is vague if money can rework to flow more ;)
Stock for stock, a thermoquad on a 340 would handle a 6 pak on same 340...and most 6 pak street cars, tons right ? ;) will lay down to a 750 on a ld340 engines the same without someone who knows how to tune and rework manifolds. Some can., most cant.
