4B11, 2.0 Shortblock-Core Required

Wanting to push your 4B11T to the max on the road course or make 500+whp on a Mustang Dyno? Your block will need to be sleeved in order to achieve those goals and do it safely!

We're offering this service to you. By sending your 4B11T block to Buschur's  we will machine it, install a set of bulletproof Darton ductile iron sleeves and ARP Main Studs, forged pistons, race bearings, line hone, I beam rods and professionally assembled.

Your good block, crankshaft and oil jets are required to provide this service. Please call us for a return authorization number before sending in your core.

If you would like to purchase this block without a core that is possible.
