The Eagle Pro Street rotating assembly for Chrysler 360 is a race-focused, naturally aspirated package. It pairs a 3.580" forged 4340 crank with 6.123" I‑beam rods and 3/8" ARP 8740 bolts, and uses hypereutectic KB -5cc flat-top 4.030" pistons with plasma-moly file-fit rings plus King XP rod and main bearings to deliver consistent operation under high load.
