Iron Eagle Small Block Chevy cast iron bare blocks feature:
* Standard 9.025 in. and tall deck 9.325 in. versions allow for greater versatility
* Raised camshaft .391 in. (4.912 in. camshaft to crankshaft centerlines) provides more clearance for stroker cranks and eliminates need for fragile small base circle cams (option for .434 raised cam also available)

* Oil pan bolt holes are relocated in line with main caps to eliminate interference with rotating assembly
* Dual starter mounts allow starter to be mounted on either side of block for chassis and oil pan clearance
* Front and rear external oil inlets, crossover and restrictor provisions provided to simplify plumbing with external pump
