Dart Iron Eagle Small Block Chevy 350 Mains 9.025" Deck, 4.125" Bore PN 31121212

FEATURES
• Standard 9.025” 
• Raised camshaft .391” (4.912” camshaft-to-crankshaft centerlines) provides more clearance for stroker cranks and eliminates need for fragile small base circle cams. 
• Relocated oil pan rails are spread .400” per side (.800” wider than stock) to increase crank/rod clearance and reduce windage losses.
• Requires use of remote oil filter. No provision for block mounted filters.
• Oil pan bolt holes are relocated in line with main caps to eliminate interference with rotating assembly.
• Big block camshaft bearings allow the use of cams with larger base circle diameter to improve strength and reduce twisting with cam-driven pumps (small block cam tunnel available).
• Dual starter mounts allow starter to be mounted on either side of block for chassis and oil pan clearance.
• Front & rear external oil inlets, crossovers and restrictor provisions to simplify plumbing with external pump.
