Pistons

I'm going to use these pistons. They're used & are part of a disassembled short block I bought. Here's the description that Summit has:

If you're looking for pistons with an unbeatable combination of performance and value, Speed-Pro hypereutectic pistons are for you. These pistons are manufactured from FM244 aluminum alloy, which contains 16 percent silicon for greater strength and wear resistance. They're also molded in the latest permanent-mold technology to ensure the precise fit and tight bore clearances that today's top engine builders demand. They're ideal for use in high performance street, bracket racing, and oval track racing, and will work perfectly with normal ring end gaps.


It says "normal ring gaps." That's kinda' vague. What ring gap should I use? The engine is a 360 with a .030" overbore. Any recommendations as to ring type?

You can use a std gap on those which most rings will come in around 17-18 if the engines bore/hone was good and that should be fine.The kbs do have a higher top ring and with the expansion rate if you butt the ring it will pop the head of the piston off,Ive actually saw one on a pontiac motor one time!.
