SmallBlock engine swap on a Mopar A-body with headers.... Never Again!

Been doing an engine swap in my Dart, for the last fkn 4 days!
318 to 360. With Doug's headers. Everything is fighting for the same location and blocking something else.
Almost none of the lower engine bolts can be reached with a normal socket wrench.
Stupid angled oil filter base large bolt is pretty much unreachable, and is now leaking ofcourse.

MOOD: Pissed!

How I long for those relatively smooth bigblock engine swaps in full size Mopars again...
Sounds like teething pains of a first timer.
I completely understand!
