Frank SNIP You can't bore a 290/304 out to 343/360 dimensions and expect it to last and etc. SNIP The statement that you can't do this, does not conform to the generally accepted story of the Service Replacement Block which is un-marked as to the size, as it is stored unfinished, but understood to be machined to the appropriate dimensions as needed for warranty repairs. There must be some fudging around capability as manufactured, although it very well may depend on what year one is talking about.
