Well, I will call the seller tomorrow and see if I can take it to my mechanic so we can put it on a lift and go over every inch of the motor and undercarriage. I too am a little skeptical. I know these stroker motors run about 3 grand alone on eBay, so this seems too good to be true. But if there is nothing me or my mechanic can find, it's mine, even if there's an issue we somehow missed, I'll still get my money back all day if not profit some. Thanks for all the advice, I appreciate it.
