			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 Last edited by AnthonyS; 05-19-2023 at 11:51 PM. Reason: typo  |
