Did the 1979 Lil Red Express come with an air pump?

i find it all fascinating. i mean, not that it makes a lick of difference for what i'm doing, but it's interesting none the less.

here's a question on the 75~76 dip in power, was that in conjunction with the debut of lean burn? or was that when they went to the 8:1 compression vs. the 8.4:1?

The dealer info stills says 8.4:1 for ‘75 and ‘76. My guess is the power loss is due to tuning changes to get the motor through emissions with the dual exhaust and no cats. Assuming the link I posted had an accurate recollection and the ‘75 and ‘76 A-Body did still had dual exhaust and no cat, outside of CA that is.

BTW, lean burn wasn’t introduced until ‘77.
