Question: Suffix code

[paul robb]

Need some help understanding the numbers stamped on the machined pad on the passenger side of my engine. The numbers are,
FO2I4YH. There are no other numbers on the pad. The car is a 66 coupe with a power-glide transmission. Any help would be greatly appreciated.

YH is not a suffix for a Corvette engine.

Are you sure it's not KH?

It was transplanted from a '66 327/220hp 4-barrel automatic pickup truck. Original '66 Corvette Powerglide engines had either an "HO" or "HR" suffix, and had the car's VIN derivative stamped on the outboard end of the pad.
