Dart's small-block Ford Iron Eagle blocks are designed to work with the stock components, but are now much more than a stock replacement. The new Dart SBF block has been designed from the ground up for hardcore racing. These new blocks are cast from premium high strength iron with extra thick cylinder walls and decks. The main webs are beefed up and fitted with steel 4-bolt main caps. All the racing technology you have come to appreciate from Dart with new features below:
- New 6 head bolt pattern on all Iron Eagle blocks for improved head gasket sealing under extreme conditions.
- Material added behind lifter bank to accommodate aggressive lifter angles.
- Enlarged lifter bosses to accommodate offset and oversize lifters.
- New center lifter oil cross over for improved lifter oiling.
