Thanks guys. I know some ring manufacturers,but not all of them, are now recommending a bigger second ring gap,but I'm not sure on that ,I've always done it the old way and never had a problem(that I knew of). Even though I think the smaller ring gaps would be more efficient I might err on the side of caution and go for a slightly bigger top gap,just in case the engine gets really hot some time.
Steve, I normally run .004"-.0045" piston to bore clearance but BRC recommended to add .002" extra. I have previously run TRW forged pistons at .0085" without a problem, my machinist took some convincing to bore for these clearances though,he said 'the piston will be like a dick in a shirt sleeve'. |

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
