Re: Ring gap
I'm a little 'loose' with my thinking, and in response to post 7, me thinks 'big' does not present any substantial problem. 'Course, I'm thinking OLD Fords, patch-um-up anyway necessary. And, NOT high-quality 'race' engines which many folks here tend to embrace.
For example, I patched up the engine in my 47 after it burnt a couple of pistons. This was (is) a worn-out engine, like .020 wear at the top of the cylinders. I replaced a couple pistons (used), and was given some .040 rings. No problem, I just opened the ring gap for a standard bore, and was not too careful about it. It sticks in my mind that .020 or more was 'good enough' in my mind. My point being, that I was very 'sloppy'. And the engine was worn out anyway, so it really needed a much more serious rebuild. The result was (and is) that it has never used any oil, and it has never overheated. Measured compression has held at around 110 +/-. Of course, this is on a low-mileage, hobby car. Am I recommending this? Heck no. But, it's been good enough for my purpose. (So, Hasting rings, and .017, would not be any problem for me. And, on a good bore, to boot.)
