If your truck is a 351M, its the same bellhousing as the 460 you will not have a problem with the drive shaft the tranny will not move. You will need 460 motor mounts for the frame they unbolt from the frame put them in the same holes as the 351 frame towers.The bucket brackets that bolt to the block of the 460 also. They have to from a 79 back truck and you will also have to have the truck exhaust manifolds cars will not work, or you can buy a set of headers for around $100.00.
Also use the truck oil pan a car will work but the drain is on the side makes it hard to get the drain plug out when its against the cross member.
Will need at least a 3 core radiator, a 4 core would be the best to keep that 460 cool.
