[QUOTE="SFO, post: 827579, member: 21864"] I R&R'd my 426 top end for the break in inspection and the small end bore of the rod was already showing some signs of galling on the right side. I ran a ball hone through it and it went another 1400 miles +50dyno pulls as a 444. The recent incarnation, or remnants thereof have included mounting a Falicon stroker cr-f rod onto the crank. It is .060" longer than stock so cutting the barrel to establish your .04" squish might not be needed. The Ampco 45 bush in the small end is the bees knees as far as bronze bushing material goes, the 5%nickel content makes those bushings as tough to wear out as they are to size... If your budget allows I would vote yes, but installed it is the price of an oem crank complete so it is a geek thing that you alone can decide. [/QUOTE]
