crank weight you state the crank weight is 50 lbs. is this correct or just an estimate?

We have a shipping weight listed as 50.8 pounds. That is an estimate and may vary slightly. Keep in mind that cast crankshafts weigh less than forged crankshafts so a standard weight cast crank will be a few pounds lighter than a standard weight forged crank.

If suppling weight for balancing of crank, we need to know piston weight with wrist pin and rings, big end and small end weight of rod with bearings. To balance a crank Speedway charges $149.99. There may be an additional charge if heavey metal is required for balancing.

what ballencer and flexplate do you use?

what ballencer and flexplate do you use?

Answers

The standard 350 crankshaft will run the 350 balancer and flexplate designed for internal balance. We strongly suggest balancing before assembly for a vibration free engine. The 383 with the balance and clearance option runs the balance plate and 400 balancer for external balance.
