Slant 6 - 360 Swap?

how hard is it to swap out the slant 6 with a 360.

EASY!

Are the transmissions the same?

NO, You'll need a small block tranny.

Will it bolt right in?

After the Mods, yep, easy

Or am I in for enough work that I should just find a Dart with a 360/318 already in it?

That would be even easier to do and save $160 in the engineswaps.com swap mounts that I used. No need for tranny mount swap or MOD, it'll fit the S/B tranny no problem.

This was a simple job to do.
