A 454, 455, and 502 have worse R/S ratios IMO its a moot point in the general sense.
If your building a super-charged engine with nitrous, why even worry about a stroker? your only gaining a measly 43 cubes with a stock bore. (not knocking a 347, I'm building one myself).
If'n I wuz U, I would check out a niv\ce siamese bore block that could take a healthy over-bore. A 4.125 bore and a 3.00 stroke gives you 320 cubes. I think a blower/nitrous car would benefit more from the unshrouding than increasing the stroke? Stuff it with a stock length rod and a beefy custom reverse dome piston with a nice thick crown.
