- Dart Small Block Chevy Iron Eagle Engine Blocks
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!
