Engine numbers - ZR-1 Net Registry Forums

Subfixer · 04-26-2022

I'm looking for the breakdown of the numbers stamped on the driver's side near the oil pan.

1990 #0116: 10ZSH X908170003 (hand stamped), date on driver's side near bell housing flange: 7/27/89 (hand stamped) both stampings very light.

1990 #2793: 10ZSH X006210006 (machine stamped), date on same area as VIN: 50590 (machine stamped) both stamping very deep.

I looked in the registry site, but could not find the breakdown.
Thanks.

An NCRS 90/91 TIM&JG is an excellent publication with reams of info and color pics. Well worth the investment.
