What engine for my Wife's 70 dart

Luke, looks like you're on the right path. Btw: Good for you building this for the wife. Very nice of you and very smart. It's always easier on us if the significant other is into the hobby too. There are still lots of 318/904 combos out there. Just be patient and find the right one. It would be nice to find one in a running car (that maybe someone is switching to a big block) so you can hear it run and possibly drive it. GL.

oh yeah, she is into the old cars. her dad had some back in the day. ever since i finished my 69 charger she was wanting her own car to drive to shows or just to cruse. but of course it must have power steering and a/c, and I'm ok with that, as long as its mopar. this car has all that, just missing the motor and trans. even has fender-tag, i posted it in another thread.
if i find a 360 with trans, what would i have to change to drop it in if anything?
