ARP torque converter bolt kit for GM 200, 700, 4L60 and 4L80 automatic transmissions, supplied as a 6-piece kit. Torque converter bolts see reversing load every time the converter loads and unloads; ARP fasteners are cold-formed and thread-rolled after heat treat so the thread root is left in compression, which is where a stretched converter bolt normally starts to fail.
This is the Chevrolet big block kit in the pair. ARP lists 230-7305 for Chevrolet big block engines only, whereas the companion kit 230-7304 is listed for Buick plus Chevrolet small block and big block. The two share an identical kit name in ARP's catalog, so order by part number. Fits GM 200, 700, 4L60 and 4L80 torque converters. ARP application list, Chevrolet big block: 396, 402, 409, 427, 454, 496, 502, 572. Narrower engine coverage than ARP 230-7304, which ARP also lists for Buick and Chevrolet small block. ARP does not publish a thread size, head style or grade for this kit number. ARP publishes no printed instruction sheet for this kit; refer to ARP general torque recommendations.
