QUALITY STRENGTH PERFORMANCE SINCE 1981<br />
QUICK INFO >>><br />
True race block which will work with most standard<br />
components. Provisions for wet or dry sump oiling<br />
systems. Great for power adders and maximum effort<br />
engines.<br />
Dart’s Iron blocks for Ford are designed to work<br />
with stock components, but are much more than<br />
a stock replacement.<br />
Designed from the ground up for hard core racing,<br />
all the weaknesses of the factory castings<br />
have been addressed. Dart blocks are cast from<br />
premium high strength Iron with extra thick<br />
cylinder walls and decks. The main webs are<br />
beefed up and fitted with steel 4-bolt main caps.<br />

CAST IRON ENGINE BLOCKS<br />
• Siamesed cylinders: Standard 4.000” or 4.125” cylinders can be safely bored<br />
to 4.185” diameter, extra thick walls prevent cracking and improve ring seal.<br />
• Extended cylinder barrels for improved piston support.<br />
• Four deck heights: 8.200” (302), 8.700” (stroker 302), 9.200” (351C) and<br />
9.500” (351W) allow increased displacements up to 468 cubic inches.<br />
• Steel 4-bolt main bearing caps are standard. Three center caps have splayed<br />
outer bolts for maximum strength.<br />
