Stroker plus boost.... LOTS O TORQUE.
Stock stroke in either block.... LOTS O TORQUE.
less stroke and less RPM will make a block live longer. But ive just witnessed TWO big blocks NA, granade from high RPM and not even beat that hard.
One was a MEGA block, the other a Hemi World block. Both 540ci range.. Both windowed the blocks. BUT... both were shifted near 7500RPM most of the years of service they put in.
NOW, Ive also witnessed a stock 360 bottom end, single turbo go mid 9's and live a long happy life until it pushed a head gasket. Still running now in my buddys dart... but he shifts it at 6200 rpm and no signs of cap walk or anything. My 2cents... keep the RPMs lower, higher gear, and solid tune up, and you will have more fun that anything plus boost noises!! Im getting parts together for my 451 ( 400 stroker) with a single 88mm S480.
Either will make any car a handfull, on the street.
my question is, whats your budget and how are you putting this new found power to the ground?
