Eagle 103523480 - Eagle ESP Cast Steel Crankshafts Details
Chevrolet - Small Block
GM engineers redesigned the crankshafts used in production small-block V8 and V6/90° engines in 1986 to use a leak-resistant one-piece rear seal. This change from a two-piece seal to a one-piece seal required a change in the bolt pattern on the crankshaft flywheel flange. The engine block, oil pan, pan gaskets, and flywheel were also redesigned to accommodate this one-piece seal. The bolt circle on pre-1986 production crankshafts is 3.58'' in diameter. 1986 and later cranks have a 3.00'' bolt circle. In addition, all cranks which use a one-piece seal require a counterweighted flywheel for proper engine balance.
Eagle ''ESP'' Cast Steel Cranks are 100% new pieces at an affordable price. They feature standard size rod and main journals with a journal finish of 6 R.A. or less. Also featured is an .092'' radius on the rod journals, main journals, rear seal and snout for increased strength while still allowing the use of inexpensive OE bearings (Ford 302 & 460 have .125'' radii and require chamfered bearings). Each ''ESP'' crankshaft is inspected for dimension, size and stroke accuracy so you know it is capable of going from the box to your block without worries. Eagle also guarantees a target bobweight +/-2% that reduces balancing time.
