How did Eric rebuild a 96 inch EVO engine?
Just a touch of black paint, and the cylinder looked like new. Eric used a set of KASTAR cylinder hold-down nuts to secure the iron cylinder in place. This allowed him to measure the deck height (dimension from the top of the cylinder to the top of the piston at TDC). He did this with a straightedge and a feeler gauge.
