Got the call lastnight, we dig today.
.......Then insulation will be placed on the inside of the foundation wall.............I'm not really familiar with garage footing/short block wall construction vs. a traditional basement footing and block walls. Should you not be putting rigid insulation on the outside of the block wall vs. inside it to protect it from freezing? Around here there would be continuous 2" rigid foam on the exterior from the footing right up to the eaves and 2" of rigid foam board + a vapour barrier under the concrete slab as well. Maybe I missed this discussion in previous posts.

OK, I see what you intend to do. Similar to what I was referring to except we'd be adding 2" of foam board on the outside of the blocks as well + using a full 2" of insulation under the slab not just around the perimeter of the block wall. Given cost of heating long term for relatively minimal money you could use 2" foam board everywhere under the floor and get an overall R10 vs. R5. IMHO.
