moving motor back @ 5"
 

i have a 54 willys wagon perched on an 87 blazer k5 chassis. the original owner did a great job mounting the body to the frame. however i have no room at all for a radiator. what i do have is plenty of room to move the motor back to get enough clearance. this is above my pay grade but i do have the confidence that i can do it with enough info. i'm guessing drive shafts will have to be re-made as well as the trans mount being moved as well. i want to keep both the 350 sbc and the th350 in it. any help? thanks
