Looking for opinions on pistons for a 340 street motor. Hyperutectic or forged pistons?
You say street, I say hyper ((street, hyper...street, hyper)).
:sign3: I have over 150 runs on my KB Hyper pistons and I just redid the engine and they where fine , I also twisted my engine to 7500 no problems550+hp and 7500 rpm with hypers... NEXT!
IF you are building a street engine and want to save some coin, use hypers.
Gonna run it high rpm (7K +), hit it with more than 125 of juice, start looking at forged.
Just gap the rings to at least the specs the manufacture recommends.
