Oldsmobile 260-455ci V-8 1967-90 - 39° Bank Angle Engines
Also fits 1966 400ci & Toronado 425ci

*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.

**Note: 1985-90 307ci engines are 39° 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.

***Note: Since 1975 General Motors divisions have exchanged engines throughout different models (ex. 350ci Chevy engines in Oldsmobile cars). Be certain of exactly which engine you have before ordering.
