I guess I didn't word that correctly, 10,000 miles is NOT a good cost/mileage, unless you are only doing a 1/4 mile at a time, I recently read a post that they had over 10k on thier stroker, so I guess it all depends on how you drive/maintain your engine as to the life expectancy. I guess what i was getting to is if cap walk was such an issue like the builder was stating in his article, then we can expect a much shorter life out of a stroker??
