Been researching piston choices for the 360 I'm building and it looks like it's either KB107 or Speed Pro H116cp. With the heads I'm using and a .039 head gasket, the KB will give 9.82:1(.012 in the hole) and the Speed Pro will give me 9.51:1(.027 in the hole). Not a huge difference, but a little. My question is which piston will be most reliable? I've heard several stories from guys that have had the KB's come apart on them. My old boss at the machine shop I worked at said he would use the Speed Pros because he knew they were a quality product and never encountered any problems with them. What are the pros and cons of each? Would love to hear what kind of experiences you guys have had, good and bad.
