QUICK INFO >>><br />
Race block available with tall deck and with raised<br />
cam location. Provisions for wet or dry sump oiling<br />
systems. Maximum effort racing engines.<br />
Iron Eagle small blocks are available in standard<br />
(9.025”) and tall deck (9.325”) versions so you<br />
can select the crankshaft stroke and connecting<br />
rod length that’s right for your combination.<br />
We raised the camshaft and spread the oil pan<br />
rails to provide extra clearance for stroker<br />
cranks. The versatile Iron Eagle block is the perfect<br />
starting point for a big cubic inch small block<br />
project.<br />
FEATURES<br />
• Standard 9.025” and tall deck 9.325” versions allow greater versatility.<br />
• Raised camshaft .391” (4.912” camshaft-to-crankshaft centerlines)<br />
provides more clearance for stroker cranks and eliminates need for<br />
fragile small base circle cams. Option for .434 raised cam also available.<br />
• Relocated oil pan rails are spread .400” per side (.800” wider than stock)<br />
to increase crank/rod clearance and reduce windage losses.<br />
• Requires use of remote oil filter. No provision for block mounted filters.<br />
• Oil pan bolt holes are relocated in line with main caps to eliminate<br />
interference with rotating assembly.<br />
• Big block camshaft bearings allow the use of cams with larger base circle<br />
diameter to improve strength and reduce twisting with cam-driven pumps<br />
(small block cam tunnel available).<br />
• Dual starter mounts allow starter to be mounted on either side of block<br />
for chassis and oil pan clearance.<br />
• Front & rear external oil inlets, crossovers and restrictor provisions to<br />
simplify plumbing with external pump.<br />
• Parts kit included (PN 32000011 - see page 118).<br />
