I would say you need to provide more information. The most critical, what gears are you planing to run? What stall speed? If I were building a street car that I wanted to be able to drive all weekend, not worry about high transmission temps, or the constrant howl from high gears, I would say run 355 -373 gears, a 2500-3000 stall, and comps extreme energy a 272 cam. Real example, I built a motor, 383, same cam, 3200 stall, 373 gears for an 88 S10. Nothing fancy, you could hear the cam, but it was not real radical. Ran 12 flats at the track yet the guy drove it to work 3 days a week without any problems.
The engine pulled nice to about 6200. Out on the street, no rice rocket, not even the 2002 Camaro or mustang could pull it.
Sound: After you get to 220, you will notice the chop, but heres more-
220-230 Slight chop
230-240 Nice chop, little rumpy
240-250 Solid chop start rumpity
250+ It barks
260 Is a plug wire off??
