IRONSB FORD BLOCKSTEELCLE

Dart Sportsman Iron blocks for Fords are designed to work with stock components, but are much more than a stock replacement. Dart 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 main caps; four bolt on the center three and two bolt on the ends, to accommodate stock oil pans. They are machined for stock roller lifters and spider. The oiling system is vastly improved over stock, oiling the main bearings first for durability in high-RPM use. Has rear external oil feed, crossover and restrict provision.
