I can buy this mustang but the guy know nothing about it he bought it at a auction. It sound great and looks good just don't know anything about the motor
If nothing can be verified with the engine just assume its stock internals with a cam. Will your buddy let you pull the valve covers to look at the valvetrain/do a cpmpression test etc?
the car was bought at a auction the supposly the guy had 3 car in a warehouse storage and never returned for them. He now lived in Califonia and was suppose to come back and never did
