Default Re: How Fast Will It Go?

from the crankshaft print--
shaft must be in balance dynamically within 3 ounce inch at any one point of reference, shaft must be in balance statically within 3 ounce inch

on the rod print there is a weight tolerance of +/- 1 gram at each end ----modern engines mostly have larger tolerances

what percentage of rebuilt engines do you think have been restored to original tolerances
