Speedway introduces our new 1-pc rotating assembly engine rebuild kits, with an optional balance job. Includes new cast steel 1-pc rear main seal crank, Speedway 5140 connecting rods w/ ARP bolts and Hyperuetectic pistons. Cranks are new so they use standard size main and rod bearings. 

All balancing is done with our state-of-the-art Hines balancer by race mechanics with over 30 years of experience!  A kit purchased with the optional balance job will ship in 24-48 hours.

NOTE: Piston rings are not included and must be purchased separately.
