This short block is a good option for mild power adders. Nitrous up to 200 HP, Turbo up to 15lbs or a smaller supercharger up to 15lbs. This short block is not intended for big superchargers as it still uses an OEM Cast Steel Crankshaft. Iron Blocks are painted Epoxy Black prior to final assembly. We take serious pride in balancing and blue printing all engines. Connecting Rods are balanced on both big and small ends to a tolerance of 0.1g, bobweights for crank balancing are built to a tolerance of 0.1g and the crankshaft is balanced to a final tolerance of 0.2g. All Bearing and Piston to wall clearances are measured and recorded to a tolerance of 0.0001" and critical measurements such as crankshaft end play, connecting rod side clearance and connecting rod bolt stretch are all checked during final assembly.
