Smog Pump Identification
Going through some old parts and found a complete smog system. The pump is #7801149 and is stamped 05521S, pulley is 3027116AU. Can someone identify application and date?

055th Day
1972 1st Shift Saginaw Plant 116 Pulley is standard, NOT Deep Groove

Re: Smog Pump Identification
It's probably a 3927116 AU pulley.
That was used on nearly every Low horse small block & 4cyl.including Corvette from 1968-77..No BB useage at all. Based on your pumps date,I would imagine it came on a 1972 model originaly.

Re: Smog Pump Identification
Other than the date, is that pump correct for other years as well? I was thinking 69-72 all used the same pump.

Re: Smog Pump Identification
That #1149 pump was used throughout 1969-71,as I'm pretty sure they changed over to a slightly different design beginning with the 1972 models and carried on from there.
