SStrokerAce, a few years ago a magazine did the very test you want. They dyno'd an identically prepared 377 and 383. The 383 made more low-end and the 377 made more top-end, but the difference was never more than 10 ftlb.

You could take one of those Motown blocks with a 4.200 bore and a 3.500 stroke,388CID-18* Brodix with 2.250I-1.750E,TIT 6.150 rods,super light crank,450Grm pistons,12-15lb flywheel and one of those 100+MM Thumper turbo's-5speed Lenco in a 25-2700lb car and LOOK OUT.The big bore would be doing something then.To the tune of about 2000HP!!!!
