It´s never been rebuilt, so it should have these specs found on Hot Rod Magazine:
"The camshaft was a 268-276-44 bumpstick and was 1968 340 hardware (as were the H/D valvesprings, dampers, double roller timing chain and pushrods). Compression was pegged at 8.4:1. All LRTs used the 1974-early 1975 360hp pistons (PN 3780071).
Rated at 225 hp and 340 lb-ft of torque, the special 360 was coded EH1."
