Dont really know the Miles on the odom was not working when I got the truck. I have the receipt when the guy bought the engine. Also it was running when I had it in the truck. Just pulled it out to clean up the engine compartment. Now Im thinking of doing a swap with some kind of other engine but just dont know what yet, Still doing my research. I would really would like to do a SR swap, but kind of iffy. what you guys think?
