Speedway introduces forged rotating assembly engine rebuild kits, with an optional balance job. Includes new 2-pc rear main seal crank, rods and pistons. Cranks are new so they use standard size bearings.
New one piece rear main cast steel crank. Standard size journals. Hyperuetectic piston set and Speedway Super Stock rods. ARP rod bolts.
All balancing is done with our state-of-the-art Hines balancer by race mechanics with over 30 years of experience!
