Crazy Auntie Di

Am I crazy? I want to drive my '82 wagon for the rest of my life, but with 289 thousand miles Irene (my car) is a getting a little worn out! She still looks good though. I was thinking about swapping the enigne to a Mustang 289 or 302. Does anyone know of a conversion kit for something like that? You see, Xzibit hasn't called me back, so...
