Dart's Iron Eagle blocks for Ford are designed to work with stock components but are much more than a stock replacement.
Designed from the ground up for hard core racing, all the weaknesses of the factory castings have been addressed. Dart blocks are cast from Premium high strength Iron with extra
thick cylinder walls and decks. The main webs are also beefed up and fitted with billet steel 4 bolt main caps.
Specs:
• Siamesed cylinders: Standard 4.125” cylinders can be safely bored to 4.185” diameter, extra thick walls prevent cracking and improve ring seal.
• Deck height: 9.500” (302)
• Steel 4-bolt main bearing caps are standard. Three center caps have splayed outer bolts for maximum strength.
• Two main bearing diameters: 302 (2.249”)
• Upgraded oiling system has been completely redesigned with a low restriction priority main oiling system with rear external oil pump feed.
• Reinforced head bolt bosses are blind tapped to prevent leaks and produce accurate torque readings. Extra thick decks prevent head gasket leaks
