A guy at my work has a 351w for sale. It came out of an '80's van. It had 150,000 miles on it when he sent it to Jasper to be rebuilt. It now has 50,000 or so miles on it. The van was scraped because it was no longer legal to drive on the road, (got to love NY winter, more rust than you can stand). My question is should I buy this motor for a swap in my GT?
