7028270 did not use the hot idle compensator. This one has a plugged HIC channel an threaded holes for the HIC cover.

I am not disagreeing with you;
I agree that it looks like this has been through at least one rebuilder.
I have seen rebuilders drill the hot idle compensator out, and others plug it.

It's not stamped, and obviously been modified from the way GM sold it - that is all.

1970 Formula 400
Carousel Red paint on Black standard interior
A no-engine, no-transmission, no-wheel option car.
Quite likely one of few '70 Muncie three speed Formula 400's left.

1991 Grand Am: 14.4 @ 93.7mph (DA corrected) (retired DD, stock appearing)
2009 Cobalt SS: 13.9 @ 103mph (current DD; makes something north of 300hp & 350ft/lbs)
