Anyone here has dyno experience or has studied the effects
of wrist pin offset ???
And what about cylinder bore offset in either
with crank rotation or against crank rotation ???
Know the net effects ???
I've offset bored blocks along the crank axis to unshroud
larger intake valves, but never tried the other ways...
its one of those things i often wondered about or thought by know i would have tried !!
I did switch the pin offset (reverse pistons in bores)
on an Olds 455 cid Stocker engine in the late 1970s
..relatively small intake port cross-sectional area
for that size engine (455 cid W30 Olds) ...from that point on the car was faster in MPH trap speeds and a little faster in ET ...but does anyone here have better evidence ??? or data ? Larry Meaux (meauxrace2@aol.com)
