Dart blocks and cylinder heads provide an exceptional value at an affordable price. Precision machining and quality control measures mean you get optimum out of the box performance. A \"bargain\" component can wind up costing far more after the machining which will be required to make it usable. Our cylinder heads offer considerable added value as well. Superior casting technology, premium materials, optimized port and chamber design, premium valve guides, hardened valve seats, rolled valve angles and CNC porting are among the available features. Fully assembled or bare heads can be ordered with combustion chambers matched to your bore size.

Description for Dart Machinery part# 31121121

Build that race engine with the right foundation. These Iron Eagle blocks are designed to meet the needs of hot rodders, stock car racers, sprint car teams, drag racers, and road racers who want a real racing block at an affordable price. Iron Eagle small blocks are available in standard (9.025 in.) and tall deck (9.325 in.) versions, so you can select the crankshaft stroke and connecting rod length that's right for your combination. There is also a choice of 350 or 400 main bearings to fit factory and aftermarket cranks. These blocks also feature a raised camshaft and spread oil pan rails to provide extra clearance for stroker cranks. The Iron Eagle blocks are great starting points for big cubic inch small block projects--you can even build a 455 c.i.d. small block.
