yea i do. when i put the motor in that is in it now i drove it around for a couole of weeks, then took it on a 3 hour trip.. this trip is a bit further so i'd like a good amount of miles on it before the trip..lol
worst case i have to take the mustang. rather not but it is an option.
I'd be worried about the machine shop not turning your block around quickly... I know for me; I'd get burned and I wouldn't get the block back till September :rolleyes:
I hope for your sake that they are quick!!
