I had a junk car engine that I practiced on popping bearings out of - it was beated down badly and took some elbow grease and a few burned gloves to get the bearings out. This is what I called the "worst case scenario" bearing swap. Anything will be easier than this. (it took a couple soakings in 2 gnarly solvents and a 450°F oven for a half hour to get those bearings out)

This engine will be much easier to do, I'm sure of it.
