340 in early abody

Any passenger oil pan will work ( front -mid sump)
I'm using a Hurts cable shifter with no issues
You'll need a recessed air cleaner
I would think any kickdown should work (but not an an expert on this)
And you'll need to modify the early A motor mounts to work.
Otherwise it's a bolt in

Oh and if you using a 727 trans you may have to knock out the fire wall a little
