Additional Features. The pistons have valve reliefs of approximately 4cc, which are positioned to accommodate the inline valve layouts of N351, GT-40, and other Windsor-type heads. Clevite bearings are used at the main, rod, and cam-bearing positions. The rotating assembly is balanced for a 28.2 in./oz. early-style flywheel and harmonic damper.
