 Dart Iron Eagle Small and Big Blocks |
Dart Iron Eagle Blocks - SB Chevy We’ve incorporated all of the advantages of our Dart aluminum small-block in a new cast-iron version. We designed the Iron Eagle block 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. 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. We also offer a choice of 350 or 400 main bearings to fit factory and aftermarket cranks. We 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 455ci small-block with Dart! We machine the Iron Eagle block to precise tolerances, eliminating the cost of expensive “blueprinting” a production block. Compare the cost of a race-ready Iron Eagle block to what you would have to spend on main caps, align honing, and machining a production block. Our Iron Eagle block is built right - and it has features that aren’t available in any stock small-block! |
- Steel 4-bolt main bearing caps resist bearing bore distortion.
- Relocated oil pan rails are spread .400" per side (.800" wider than stock) to increase crank/rod clearance and reduce windage losses.
- Oil pan bolt holes are relocated in line with main caps to eliminate interference with rotating assembly.
- Rear main cap has provisions for a wet sump oil pump.
- Dual starter mounts allow starter to be mounted on either side of block for chassis and oil pan clearance.
- Side and front engine mounts accommodate any type of chassis mounting.
- Fuel pump boss mounts a standard small-block mechanical
fuel pump (requires .200" longer big-block
pushrod). - Two-piece rear main seal fits standard racing crankshafts without adapters.
- Raised camshaft (4.912" camshaft-to-crankshaft centerlines)
provides more connecting rod clearance with
long-stroke cranks. - Optional big-block camshaft bearings allow the use of cams with larger base circle diameter to improve strength and reliability.
- Chain, belt, and gear camshaft drives are available for Iron Eagle blocks.
