Got the engine up on a stand yesterday and started measuring things. The crankshaft is stamped .010, the journals are smooth and it plastigages .002 to .003. The camshaft looks like new. That's the good part.
But wait...there are NO SLEEVES at all in this engine. The pistons were running in the bare block. I'm not sure how big a problem this is.
More information: the pistons are 3.265 diameter (.080 oversize?) They have 4 rings and they have a dome shape on top.
The bores measure 3.271 to 3.272 at the bottom and 3.276 to 3.280 at the top. So I'm looking at .002 to .004 out of round and .005 to .007 taper. MARGINAL according to my FO-4.
My question:I'm on a real tight budget, can I get by with just a hone and re-ring...or do I need to get the block bored out for .090 sleeves and new pistons?
