the best street motors usually produce raw torque. something you don't turn a gawd awful amount of rpms id go big block. or stroker. but if you get stuck with doing a sb. iron heads even if they need work are usually more cost effective. if you find the right shop even better. if you spend a total of $500 on machine work on some $150 iron heads youve got some bad ass heads for like $650. id go like 283 .030 over with the 327 crank. thats like a 302 get some iron heads get them worked. go solid roller cam because of the steeper lobes and the bigger lobe seperation, and more lift. go like 12:1 if you can legally and cost conciously. that would be me that combo makes a decent fast revving motor for the street but the comp is a little high for most ppl. if you want more specs lemme know i could go on all day with good motor buildng tips. rpms+speed=dollars squared
