The Eagle cast crankshaft for Chevrolet 383 applications is an internal‑balance design with a 3.750" stroke and .092" fillet radiuses for added strength while still accepting OE replacement bearings. The crank is intended for pump‑gas, naturally aspirated road cars and specifies a minimum 6.000" rod length requirement for proper connecting rod clearance and assembly geometry.
