Not Like the Others . . . BTSV

We got this lower end together.  Very nice.  It runs a close set of flywheels.  We notice everything is real tight in some of these older engines.  The flywheels are close to the cases, the scraper . . . the rods can be very close to the baffles . . . and a bit different assembly than overhead valve motors . . . they omit a thrust washer, etc . . .
