Cast 3 3/4" stroke crankshaft for later model, one peice rear main seal block. Use with 5.7" rods and 153 tooth flywheel or flexplate (factory external balance), and 400 cu.in. type, eccentric balance harmonic dampner. Will not work well with "LT1" engines as they have a hub/balancer combo that is for an internally balanced rotating assy, and that's why I don't need it. Purchased new from Competition Products and never used, still in box. $125
