If u offset gring the crank .060 u will gain usually .050-.055 depending if the crank was turned before or how much wear was on it to start with.they will also index all the throws to make the stroke the same for all cylinders (never assume it is). u will need .060 bearings. one trick= more cubic inch+1point in compression.I have this done with every low comp engine. What this does is slow down the bearing speed ,which makes for less stress on the crank.I have done this trick with both forged+cast cranks and have never had a problem, even with brand x stuff. It moves the centerline out so it is recomended to rebalance the crank.U have to remember the stroke increase is x2 because it pulls the piston down+ also pushes it up that much farther.It costs usually twice there labor rate to offset grind because the is alot more involved in the setup time.............Contrary to what other people think balancing is the only other added expence , which should be done at any engine rebuild, whether it is for your daily driver or your racer..............older+wiserkimmer......................................Any questions?.....feel free to ask.........I dont claim to know everything, but I do know something.......Ofcourse, like anyone else my age I may have forgot something.........
