855.313.9176Quick and Easy Returns
Return PolicySpeedway 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 (must be purchased separately, part # 91510200). 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.
Chevy 434: 4.125" bore x 4.00" stroke
NOTE: Piston rings are not included and must be purchased separately. Use Style C rings.
