Please go here K-B and study carefully to determine the correct end gaps for your K-B hypers, which I'm assuming is the piston you were referring to. Proper ring gap is critical for these. Too close and you will melt them down in short order. They run wider gaps than would be considered conventional for most other pistons in a similar combination. I used them in a stock bore 350 build and the gaps were .026" top and .018" for the 2nd ring. I would not be concerned with using them in a properly built engine that made 450 CHP or a bit beyond. The 350 I used them in made 370 at the rear wheels and was a good, reliable street engine that was also raced.Last edited by Bodacious; 10-13-2007 at 06:49 AM.
Yes, you can build an engine that's fast, cheap and reliable.
Pick two....
