Return PolicyKeith Black Hypereutectic pistons are favored for their improved power and reduced scuffing. The unique design & manufacturing processes combine to produce a rigid piston, which will rock less in the bore improving ring seal. These T-5 heat treated pistons also offer reduced thermal expansion, which allows you to run tighter clearances and allows the piston rings to seal better and minimize blow-by.
For S/B Chevy 350 c.i. (4.000" bore x 3.48" stroke).

I measure absolutely everything I receive immediately after opening the box. The pistons are as accurate as could possibly be without spending considerably more money.

I was wondering if I could order these in a .030 oversize for a sbc? Also do you have to use full floating pins? I'd like to use the stock style press in pins if possible.
