SB Chev 305, 350 & LT1 Cast Steel Crankshaft 3.480 Stroke, 5.700 Rod, Internal Front, External Rear Bal

The 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.
