5.3 = smaller bore, same stroke, same crank as ls1

There is a build thread on a old school Nova on theturboforums of a 5.3 pushing 1200-1400rwhp(I can't remember) with a stock crank, forged rods, forged pistons, All Pro heads, and a LOT of boost. Stock crank bolts, stock size ARP studs. Still not pushing water.

ls1/ls6= 3.897 bore x 3.622 stroke
5.3= 3.78 bore x 3.622 stroke
4.8= 3.78 bore x 3.286 stroke
6.0= 4.00 bore x 3.622 stroke
6.2= 4.065 bore x 3.622 stroke
