Street Spec Standard Shortblock

Designed for the low noise and long life essential for a daily driven street application while easily handling increased power outputs and weekend track use. Buit to exacting strandards from the highest quality components. The Street Spec shortblock now features a much higher performance rod manufactured to our specific requirements. Rods are forged from heat treated & stress relieved 4340 chromoly. Pistons are from Cosworth and utilize a slipper skirt design for low frictional losses and an advanced boxed bridge forging for high rigidity and minimal weight. Crankshaft is an OEM forged and induction hardened unit. Bearings are King XP Gold offering extreme load carrying capacity and high temperature resistance with the tightest control of shell thickness in the industry. Assembled using all new components.
