The engine didn't seem that tight, but I might not know what I'm talking about on that. When I got the engine, the main bearing bores were out of line (had it line bored). Then, it was really tight.
The bearing clearances on # 1 and #2 were between .001" and .002" (a bit over 1.5 thou) measured with a good micrometer and confirmed with the plastigage.
