New Sleeved 84mm Billet Hayabusa Block
These blocks are the same as we use on our Championship winning Pro Mod Hayabusa! They lasted twice as long as nickasil plated bores in our big nitrous (400+ HP Shot) application. They are 3.50″ tall, .040″ taller than stock with stock bore spacing. Perfect for Gen 2 crank with no spacer. The bore is finished for 84mm pistons and are ready to run after final cleaning. They are in stock now for immediate shipment!
