440 in '65 DART
I'm not quite sure moving the engine back would be worth the trouble. Between firewall clearance, trans tunnel clearance and possible oil pan/centerlink interference, what would by moving the drivetrain back a couple inches?
With the engine in the stock location and V8 centerlink, you'll have plenty of room for the oil pan. Here are a couple shots of my pile.
Just curious- What rear suspension do you plan on running?
