Forged SB Chevy Rotating Assembly, 350 Flat Top, H-Beam, 5.7 Rods
Build Your KitYou're almost there! This kit has an option or two for you to select. Let us know which options you want for your new kit.
Speedway introduces forged rotating assemblies, 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. All Scat 4340 cranks are 2-piece rear main seal, internally balanced and weigh approximately 51-55 lbs.
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. These rotating assembly engine rebuild kits may require additional charges for heavy metal.
If you are going to run this crank in a sprint car motor, you must have the crank flange turned down prior to balancing the crank to allow it to go through the motor plate.
NOTE: Piston rings are not included and must be purchased separately. Use Style C rings.
