Crankshaft Q's....
 

Want to build a LQ9 from misc. parts....I have several 5.3 truck crankshafts in good condition and several LQ9 piston/rod setups but no true LQ4/LQ9 crankshaft. It's my understanding that even though the strokes are the same and the crank has the same #'s, the bob-weights are different?.... Yet, some say it doesn't matter.... Drag race motor only, no street time. Anyone got the skinny?...

Some one must know?????.....
