Offenhauser 6x2 log intake.I'm pretty sure this thing is NOS. I can not find any gasket
residue on any of the surfaces and the runners look really clean. Fits pontiac 1955-1960 (287, 316, 347, 370, 389). Pretty rare piece that you don't see very often, especially in this condition. $400.00+shipping Will consider trades of Chevy 235 speed parts.
