NOS GM SBC 350 pistons 3991491
Hi Gang, found in the back of an old machine shop - apparently forgotten about from the mid 80s - the date on the beat up and dirty boxes is 1984.
They are unused and NOS but could stand cleaning before use of course.
They are part number 3991491 - cast number 3991479 and are the desirable 0.030 over units. These are for the non HiPo, garden variety small block 350.
Always nice to have real parts - keep your GM all GM. Know what you're getting.
Hard to find IMO.
200.00 PPG plus shipping. That's only 25.00 per slug!
Cheers Friends,
Anthony
