Is anybody around N.C. area interested in a cheap /6?

The 198 and the 225 used the same block casting so the casting number is no help. The stamping you are looking for is under the alternator bracket. The bracket has to come off to read it. You will find a number something like TT 225 XXXXXXX 2. I've spent almost 3 years looking for a set of 198 rods. They ain't easy to find.
