    The Dart Iron Eagle eliminates the compromises found in production blocks. Iron Eagle small-blocks are available in standard (9.025") and tall-deck (9.325") versions so you can select the crankshaft stroke and connecting rod length that's right for your combination. Also available is a choice of 350 or 400 main bearings to fit factory and aftermarket cranks.

    Dart raised the camshaft and spread the oil pan rails to provide extra clearance for stroker cranks. The versatile Iron Eagle block is the perfect starting point for a big-inch small-block project - you can build a 454ci small-block with Dart! Dart machines the Iron Eagle block to precise tolerances, eliminating the cost of expensive "blueprinting" a production block. Includes coated cam bearings, freeze plugs and dowels!

    Features:
  • Standard 9.025" and tall deck 9.325" versions
  • Raised camshaft .391" (4.912" camshaft to crankshaft centerlines)
  • Relocated oil pan rails are spread .400" per side
  • Siamesed cylinders: Standard 4.000" or 4.125" cylinder can be safely bored to 4.185''
  • Oil pan bolt holes are relocated in line with main caps to eliminate interference with rotating assembly
  • Main bearing bores are available for 350 (2.45") and 400 (2.65") bearings
  • 4 bolt billet steel main caps have splayed outer bolts
  • Big block camshaft bearings allow use of cams with larger base circle
  • Dual starter mounts
  • Front and rear external oil inlets
  • Scalloped outer water jacket walls
