She’s done. In this article, we’ll cover crankshaft balancing, valvetrain and crankshaft assembly. How do you like the plug wire routing? I’ll cover this in a later article installment.

These are intended for a bore diameter of 4.268″ (1/16″ top, 1/16″ 2nd, 3/16″ oil), requiring a custom [...]
WE BALANCE AND BEGIN ASSEMBLY text, photos and assembly by Mike Mavrigian Crankshaft balancing was next on the agenda.
