*Note: If your hydraulic lifter preload is excessive, this can be easily remedied by using Crane's rocker arm bridge shim kit 270-99179-1.

Conventional hydraulic, mechanical, or roller camshafts and lifters can be installed in these engines if a thrust spacer is fabricated and the appropriate kit components are used.
