Wells its for a 5.7 to a 6.4 swap. Theres 140k on the current motor, it blew the timing chain and bent a few valves at the same time. Over all to do a correct fix with correct machining it will only fall short $1000 from a used motor and I can keep mine. Its funny how all the used engine companies have the same motor at about the same rate with the same milage . Looking at 6.4 for 4k and one at 5k.Jasper...... Why go used? Rebuild your own.
