Refer to page 374 for the fast and easy way to check hydraulic lifter preload. If your hydraulic lifter preload is excessive, this can be easily remedied by using Crane’s Rocker Arm Bridge Shim Kit (99179-1). Refer to page 324 for details. NOTE: 1985-1990 307 cu.in. engines are 39º bank angle and are equipped with hydraulic roller camshafts and lifters. Lifter diameter is .921”. 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. Since 1975 General Motors divisions have exchanged engines throughout different models. Be certain of exactly which engine you have before ordering.
