**Customer must supply good, usable block and crankshaft cores for this service.**

The foundation of our Boostin Performance Short Block is a freshly cleaned, bored, and honed engine block. Before the block is ready for assembly, ARP Main Studs are installed and the mains are then line honed. The crankshaft is Magnafluxed, balanced, and polished to a mirror finish. What sets our motors apart from the competition, is our precise machining, attention to detail, and some special tricks we have learned along the way!

This Sleeved BP Stage 3 option is the strongest most potent 4B11 short block package we offer! The stock 4B11 block is a open deck design which is not ideal for high horsepower applications. The Darton ductile Iron Sleeve takes care of this issue by completely replacing the sleeve and also fixing the open deck design flaw. I-Beam rods are employed to make use of the short block, which is capable of 900 horsepower, reliabily.
