eh well you got me, you got a deal
anyways imo bottom line is he knows his engine and condition of his accessories and wether building or swapping you would want to replace certain parts, so far as cost effectiveness sticking with what you have is a plus. besides im used to being slow haha so i would take my engine off a fresh build any day than picking up someone elses engine that might of been abused. in the end its up to the op
