I want to say the crank isn't true to spec judging by the slight hairline scratches in the bearings/journals already. That's just another thing he should have checked before assembly.
The #2 and I want to say #5 pistons appear to be what was causing the friction. I haven't checked the bore but it appears his honing isn't correct in those cylinders. The rings completely compress into the pistons and cause the skirts to rub the cylinder walls.

Something must be going on then because when he checked my crank and bores in the 88's TPI 350 he said all was good and had all the pistons pressed. Sure enough when I assembled it, it was exactly what he said it should be with the plastigauge and I was able to easily turn that motor even with the timing chain on. Not defending his work there because you're right something is definitely off, but I'm wondering if he might be rushing jobs..... Still he should have at least called up and said something was wrong if he found something before proceeding. Providing he is the one at fault. Unless he had someone else put it together........ I sometimes see another guy in the shop helping him.
