? Isn't the 400 still a mouse motor, same block as the 327, 350, etc.?
The Chev small block used to be a fairly common swap with reasonably
readily available adapters. I'd almost guess the engine management to
be more of a PITA to get right.

As for other options, get a 4.0 I-6 Jeep and check out folks like
Clifford Engineering, Hesco, or JRE for stroking up to between 4.5 to
4.9 liters. Or pick up a turbo conversion...or both stroke and blow.
