So i have done my research and upgrading my motor to a 5.8 is a go. I called my friend at Ford and he told me some things to look for and i found out the 5.8 is a little larger but should work for the motor came in the truck. I am hoping to call on you guys when i get into a little trouble, for example motor mount does anyone know if i have to change them over to the 5.8 mounts, will i have to fabricate something? I know i have to change the accessorie mount, no big deal like 2 on there. So does anyone have any suggestion before i get started ... and i will be taking pictures of the swap ...
