1970 swinger build
Looking good Jay, same route as me.
Was a 318 and 904, now going 360, 727, and a 8.75
I also changed from non power drums to power discs up front.
A couple of things I came across, if you move decide later to go to a 727 box you'll need to make sure you have the 360 converter. Also if keeping a column change you'll need the right linkage. I just binned the column shift and went for a floor shifter.
You'll also need the right engine mounts for a 318 to 360 conversion
At least you live in the US, can you imagine how much this stuff costs over here in the UK !
