Anyone know what the factory tolerances are for the 5.0's?

What i mean, like, what are the factory acceptable bearing clearances, piston to bore clearance, ring to land clearance, anyone know?
Im just curious about what the 'ford' acceptable clearances are


The reason is because the 5.0's are very durable little engines indeed. I just got done tearing my buddies 87 302 apart for a rebuild, and ill be damned if that wasnt the best condition ive ever seen on a engine that had 230,000 miles on it. The cylinders only need honed, the crank isnt out of round, the only place we saw notable wear was on the rod bearings, but he ran his engine hard. So im really impressed, all the 302's ive torn down are older engines, like pre-1975. When i built mine, i just started with a summit block and a stock 1970 crank. Im very impressed.

But im very curious what the factory acceptable tolerances are, if anyone knows i would appreciate them alot.
