The Racecar, no kickdown, I have a manual valve body 350TH
This next pick is the Blue 71 Camaro. It's all street, AC, Cruise, and the kick down. The car was a 2bbl as most Camaros were. The Q-Jet has different brackets. The bracket was bolted to the carb if I recall correctly for the Q-Jet. If you have a Z/28, the carb & intake and bracket should remain as is, maybe up grade the 4150 style 780 vacuum secondary Holley to a 650-800 cfm DP.
Holley #1850, Vacuum secondary 600 cfm on an Edelbrock Performer Intake.
I wanted a Q-Jet for it, but I couldn't find one that was worth the price. So I bought the Holley new for less than a rebuilt Q-Jet.
