It is a fair amount of work. Depending on what you have already, it may run into some decent money on parts also. Depends on if the 351 is fuel injected or not. If not you will have to get a 351 lower intake, 351 fuel rails, and 351 fuel injected truck dist., along with the rest of the fuel injection parts off your engine swaped onto it to get it running with the computer in your car. Also hood clearence has to be addressed, along with 351 swap headers, damper and pulley conversion to keep the serpentine setup. Also the flywheel off your 5.0 won't work on the 351. And more thats slipping my mind right now, but those are the pricey items already listed. | 
How much work is involved in dropping a 351 in 95' GT ?
