1BAMF shortblock is what you have here! This is the sickest combination of parts that Buschur Racing could cram into a 4B11 block!
The stock 4B11 internals have been removed and the shortblock has been machined to accept the new Manley Performance 2.2L stroker kit which includes a set of Manley turbo tuff (I-Beam) connecting rods and Manley Performance forged & coated pistons. The new Turbo Tuff crank features uniquely designed, ultra-lightweight, fully contoured counterweights resulting in reduced windage and maximum performance.
Along with Manley stroker kit the block has also been machined to accept a set of bulletproof Darton ductile iron sleeves to make this the ultimate Evo X shortblock! This block is a must have for any of you hardcore Evo X owners. This block will easily handle over 500whp on a Mustang Dyno.
In a nutshell.... this shortblock assembly is ONE BAD ASS MOTHER ******!
