Tell me this noise isn't what I'm afraid it is.

If I understand henry's post correctly, one cylinder was sleeved and the remaining seven were bored. Anyone that has good experience building engines knows this is a big no-no.

What is not good with one sleeve?

I'm not sure exactly how it works but the same size of pistons went into all cylinders so I'm assuming that the one that needed the sleeve was bored slightly larger to fit the sleeve in. No problems now for 20,000 miles so far.

If he bored that sleeved cylinder to match the others, that's a good thing.
I have seen engines wherein only one or two cylinders were sleeved and the bore(s) were not matched to the others.

Not a thing as long as ALL the bores are of the same diameter.

I might be off base, but who would take and engine in to get rebuilt, and be told:

We need to sleeve a hole"

Okay...

Then the shop would order 7 pistons at ones size, and one at another?

Have you actually seen this?...I'd be extremely surprised...again...talking shop work, not when Bubba took it in and used what he had.

And realistically, what would a 1/2 cube of inches, and .01 of compression, affect the performance of an engine like a FH V8?

My personal opinion, is if I had a 60 over block and a standard sleeve size in a hole,,,no one could tell a bit of difference in a street build.

Actually this method is all too common. Even today engines rebuilt by Jasper, a very large corporation, does this as a matter of course. They go the "whatever is cheaper" method.

In a flathead it may not make a huge difference but it will make a difference.
I suppose it all boils down to doing a job correctly or doing it half a--ed.

Some mechanics are fast, others half-fast.

I would be more concerned about the imbalance created by different sized pistons. I don't think anyone who would bore just one hole would balance it.

I see your point, I suppose a large rebuilding house could save a buck or two per rebuild and over the course of time it would add up to some decent profit.

Sad thing.
