In my personal case, I have a WT code replacement block in my '65 GTO and would not want or need a WS code block ever, since I have the original protect-o-plate which shows the original E.U.N, which would not match the original, blown up WS motor without a re-stamp. I think Bart is right on with the $1500 price tag. I have built up '66 vintage 389's .060" over and have used std. 400 pistons with 068 cams with zero issues. If I built a 389 today, it would get custom dished slugs.

I'm the same way with my 65. I seriously doubt my car had the original engine when I bought it in 1980, and the currently restored car has a mid-66 block in it now. I know it is not correct because the EUN on my protect-o-plate puts the engine in the late june/early july approx range of 1965, and my invoice date was May 25 65.

So, having all the documentation I have proves that my engine is not correct or original, and I certainly don't plan to try to change/restamp anything. Lots of folks blew their engines up!
