You guys should be able to drop it in without tearing down the nose. I put my engine in/pulled the old one with my radiator still in the truck. The problem I ran into was since the 6.5 sits back so far, I had a hard time getting the bell housing area back under the firewall. It might have been easier if I had the intake off,but I had already swapped it over....:mad2:
I damaged my glow plug relay so it no longer worked, because I also had it on the new motor....
Since I have a 6" lift, and 37" tires, I just let the air out of them, so the engine lift would clear the core support with the engine hanging from it. I couldnt have pulled a piece of paper out from between the engine oil pan and the core support, but hey, it worked.....:thumbsup:
