Measuring cylinder taper with feeler gauge and ring.

Well, I measured my "extra" 340 block, using ring and feeler gauge method and my cylinders were avereaging .006 so I am thinking a honre and rering with standard size pistons would work. keep in mind most guys would say take it to a machine shop, but i am into low budget type 'any guy could do this at home" type things. The measurement as i described is purely to determine if an overbore is necessary. I am thinking I can hone and re ring. In worse case scenarios the engine may consume oil etc if the taper is too much. Nothing like adding a quart a month but you have no leaks LOL!
