I appreciate the replies. My motor will be torn down shortly. Had a failure of some kind. I know it wasn't the pistons, but I am always looking to build bigger and stronger if I have to go into the motor.
My truck gets used pretty hard. It went 50k with 300+ 1/4 mile passes at 800ish hp, and 20k of that was towing. So the general consensus is these are stronger than the normal mahle race cast piston?
Yes Verlon, that's is how this design arrived. Mr. Fingers is way smarter than I am and has all of my confidence so if he tells me that they are stronger and I need to try and prove otherwise, that's my goal! It's all in how you make your power that will dictate longevity. We just finished an lly build on a twin truck that cracked 6 pistons and bent all the rods with stock injectors& cp3 no lift pump and had 59,000miles on it. It only dynoed 525hp with the tuning that was in it when it failed. I'm sure the tuner thought it was conservative but the results say otherwise. I plan on running these pistons in my railcar when I put it together.
