Don,

The crank was turned 10/10 and reinstalled. Rods were the originals out of the engine, magged, reconditioned, sides ground, shot peened, new ARP bolts, and reinstalled. Pistons were new KB's. They needed a touch of valve clearancing. Flywheel is FMS 157 tooth billet 28 in/oz.

The iffy piece, so far, is the FMS SFI balancer. It is a two piece unit with the small counterweight that bolts on from the rear before installing. I recall the instructions that came with it saying not to install the counterweight if the engine was internally balanced. Have you ever had any balancing problems with these? How does one determine if one has the 50 in/oz, or 28 in/oz counterweight.
