1970 Olds Cutlass W-31 442 W-30 Tach / Clock
*******SOLD*******Original 1970 Olds Rally Pac tach and clock. I have tested the clock and it does not work. The hands do adjust as they should. I am not able to test the tach. The tach pointer does have a good bounce and stops at zero. A good sign. PM me if interested.

Good question. Both were same. Seems based on the peak hp specs of both W30 370@ 5200 and W31 325@5600 the both could have been a little lower. However the special springs used on both engines allowed for a higher rev without float.
