Ford 390 FE - Build A Low-Buck Street/Strip FE

Dale Pelvit at R&R Performance power-honed the bores to 0.040 oversize. Each piston was measured to confirm size consistency from piston to piston, and then the cylinders were honed to match for a precise skirt clearance. Three different sets of stones and one bottle-brush hone were used to achieve the desired cylinder wall finish. Pelvit says, "The surface finish resulting from this technique yields peak cylinder bore sealing and performance with today's modern piston and ring packages." View Related Article
