old time, chevy engine combo with newer part choices

while this has always been a combo that produced good power, simply adding a 3.5" 0r a 3.75" stroke crank, allows even greater power
if the correct parts are used, , yes you can in theory make more power per hp, but not more total peak torque or hp

or put differently, sure a shorter stroke and larger bore makes impressively higher power numbers, at much higher rpms,
but added displacement can make even more total power to the engines power curve and results in a faster car if the correct gearing and compression is matched to the correct head flow, cam lift and duration and LSA and compression, this generally requires a 12.5:1 or higher compression if you use gas or E85
