Look for a bigger truck with a tach ie C40/C60. a lot of the larger trucks had 6's and tachs. If you find one in a cluster that's not in the truck, look at the back of the tach. I don't know how true it is, but someone said a V8 tach is stamped "V8", and the 6 tach has no stamping. Mine has no markings at all, but the air gauge gave it away as a bigger truck.

Good luck!
