Hi, I am a new member here, this being my first post. I have a 94 k2500 that had a 6.5 diesel originally. I pulled it out and swapped in a 6.2 red block. Unfortunately I dropped a valve shortly after swapping it in, and destroyed the number 8 piston, cylinder wall, head, and turbo. I’m hoping to build this next engine to last longer. My biggest concern is fuel economy, with decent power (enough to pull a 13,000lb skid steer with ease). My theory is that if I build this engine for say 600hp, and then turn the power down to between 250-300hp, I just might have an engine that will last many years. This engine is another crack free red block, cast on 3-2-81. I will be studding the engine both top and bottom end, cast rockers, high flow water pump, super 54 turbo for reduced drive pressure, balanced rotating assembly, fluidamper, hi-pop pressure injectors, with 6.2 heads and pre cups for fuel economy. I’m sure I’m missing something but I don’t have my list with me. The engine came with 20 over sealed power hyperutectic pistons. Anyway, after doing a little research on these pistons, I found that they don’t handle boost very well. This engine will probably not see more than about 15lbs of boost, but it’ll see enough boost to shatter these pistons according to what I’ve read. So my question is, where can I find stock high quality pistons for this build, and can you point out errors in my build? This is my first full out build, so any advice y’all can give is greatly appreciated. Again, although a little extra won’t hurt, this engine isn’t being built for power. My goal is extreme fuel economy, and engine reliability. Thanks in advance!
