Im shipping out one of my stock engines and $200 to a guy in kansas which in turn he is going to send me his bottom end which has a 4mill crank, override, and lockup with a set of stock bore, stock ported jugs as he was running a cub (keeping those) and now for some reason want to go back to mostly stock. He told me to ship it in a cooler as there cheap and pretty "safe". My question is, what would you guys do as far as paperwork incase this guy tries to fuck me over? He wants me to send mine first then hes sending his. I got feedback from a website he belongs to and looked at his feedback on ebay and its 100% with 364 tranactions, and hes been a member since 01'. Should i have him FAX me over some kind of bill of sale or somthing and/or will paypal back me up if he rips me off? thank you!!!!!!
