Shelby's FE
alloy block delivers superior bottom end stability at high rpm. This is
accomplished by Extended skirt design, 2, 3, 4 main caps are cross
bolted with 4 cross bolts. Main caps are billet steel and cap alignment is
further enhanced by integral dowel sections in the main studs, and Steel
caps allow moderate bearing clearances for cold starts.
Centrifugally
cast ductile iron cylinder sleeves are fitted in the block, with an
interference step fit that creates precise, non-shift sleeve positioning.
Cylinder walls are siamesed and revised cooling passages make street or
race track cooling problems a thing of the past.
The block
requires special Shelby head studs, available separately. Unlike a stock
block, where the head bolt threads start at the deck surface, the Shelby
studs threads are positioned adjacent to the cylinder bore bottom. This
configuration delivers maximum gasket seal/retention and minimum cylinder
bore distortion when the head is torqued to the block.
