I drive a 1994 KW T800, it has a 3406 in it but I’m not sure which series it is. Casting on the head reads 018402 and 3K04. There was no tag on the valve covers as I have read about elsewhere. Are these the numbers needed to ID it? If so what is it? I think it’s a C but it could be a B too I suppose.

The needed number is stamped on the rh side of the engine block, pass side.

I've seen them stamped mid-block on the driver's side as well.

If you call the dealer with the VIN number can't they tell you the exact model of the engine?

In the door jam it might have a tag somewhere that says “3406peec” or 3406atac” if it’s the later, it’s a 3ZJ engine the peec engine has an 8PN serial number..........unless the engine has been swapped.
