Craig,
You may want to go back to 4:56 or even 4:88. I have a buddy with a similar combo to yours, but with 4:30 gears.
His motor is a 408 stroker, Edelbrock aluminum heads that have been ported, a much bigger carb than you run, compression similar to the 11.5 you are looking at, similar stall convertor, 904 trans with low gears. Car is somewhat heavy at around 3400 lbs (67 Cuda FB)but it's best runs have been 10.98 @ 121 at Vegas and then 10.92 @ 123 at Fontana CA

IMO the 4.30 gear is one of the best overall 1/8th mile, 1/4 mile gears around.

4.10's on a 28" tire and a stroker seems to be on the fastest smallblock stroker a-bodies around here.. so with 30" id say 4.30 should work well.and keep that converter effecient..fwiw.. cheapst.
