Wow this thread took a turn . Went from talking about pistons to how much dodge sucks , dodges were good back in the 60s & very early 70s. Anyway we are being infiltrated by dodge , thats worst than chevy . My 95 302 when it was stock before the HO would rev to 5000 ok , that was a roller mass air motor not sure about the 86 , i just don't think theres that much power up there unless it is a HO ?? Lew
