Re: Stocker Pistons....Pontiac
My sons old 318 Engine was a TRW engine with lighter weight pins,
It would run about .8 - .9 under in decent conditions under current indexes.
The lighter better pistons with TriCity Rings were about .15 to 2 Tenths faster,
but half of the difference I would probably attribute to the rings and half to
the pistons.
