The Eagle IMCA‑legal cast crankshaft for Chevrolet 305/350 features a 3.480" stroke with lightening holes in all throws and .125" fillet radiuses for added strength. Because of the larger fillets it requires chamfered or narrowed rod and main bearings. It provides a competition‑oriented, rules‑compliant crank option when IMCA legality is required.
