used to use the World 9.025 deck block. From Scott's site:
"
We Build Our 454 Small Block The Right Way ... 9.325" Race Block With Only A 4.185" Bore And A 4.125" Stroke Crank For Extra Torque. No Head Gasket Problems And No Cylinder Wall Issues In This Baby!
"
Mitchell's finishes at 4.25" x 4.0" for iron; 4.125" for aluminum. NO warranty claims for head gaskets or walls on the World-unless they were sprayed.
