Exactly what you've been waiting for! 360 and 401 AMC Pistons.

Wiseco Performance Products and K1 Technologies have teamed up to release a new Sportsman series type piston and rod combination for the 360 and 401 AMC engine. Wiseco and K1 have designed pistons and rods that are well suited for anything from rock crawling to race to restoration.

Wiseco has added this exciting new lineup to the Pro Tru series of Sportsman type pistons, maintaining a pocket friendly price with high end durability and design. Using input from today’s leading AMC engine builders, Wiseco has released both a flat top and reverse dome piston for both the 360 and 401 engines in popular oversizes. With thicker decks and optimized ring lands, these pistons will easily handle a 250 HP nitrous system with proper tuning. These pistons kits come complete with Hastings plasma-moly rings and anti-friction skirt coatings, as well as HD pins and clips. Symmetrical valve pockets can accommodate today’s larger valve sizes and specialized cams. With dish and flat top offerings available, enthusiasts can tweak compression rations from 9.5:1 up to 13.5:1 with selected components.

AMC engines have always been potent performers. With today’s cylinder head and camshaft offerings, it has become obvious there is a need for stronger bottom end components. K1 Technologies has taken a long look at the AM OE rods and worked together with AMC racers to design a dedicated rod that corrects OE geometry issues, while dramatically improving the bottom end strength of today’s AMC engine builds. Using 4340 H-beam forgings paired with K1’s own proprietary asymmetrical thread design, ARP 2000 bolts, K1 has designed an extremely durable and lightweight rod able to handle horsepower levels these engines are capable of today.

Wiseco’s AMC piston kits come complete with rings, pins, and circlips needed for your engine. The kits retail at $767.85. K1 Technologies connecting rod kits retail at $538.63.
