I was always under the impression that "it should fit" , "it's gotta fit in there", "the shape of the frame rails and headers fit together" ...

With the engine in a OEM V8 location for our trucks, none of that happened.

With a bit of ... hacking stuff apart, conservatively speaking, things kind of fall together as i hoped they would. The engine needs to move back another 2" and then it's home i think.

Installed the lift tool, broke out the grinder, hacked a cutout into the floor after the firewall left the body. Now see for yourself.

The headers seem to touch but they don't. Actually there's like 1.5" of clearance around them. I could not install the engine with the headers attached, but they "rolled" into place very easily.

Now to break my head about engine mounts...
