I disagree because.....
By Royce Peterson - 08/02/2003 5:08:14 PM; IP 67.29.197.192
There is no listing in the Fomoco 1968 shop manual for IMCO equipped 390GT engines. For example the specification chart on page 8-127, all 390GT applications are Thermactor equipped. There is a small difference in 390GT auto and manual engines that required a different tag number for each in the Master Parts catalog. The carburetor calibration was different and manual transmission cars received a dual vacuum advance while auto trans equipped 390GT's needed only single vacuum advance.

Another great place to look is in the Ignition system schematics for vacuum hose routing. Page 9-27 details the only two schematics for 390GT. There is Figure 41 for Automatic transmission 390GT's with Thermactor. And right below it is Figure 42 which shows 390GT with manual transmission and Thermactor. There is no schematic for IMCO (non - Thermactor) in a 1968 390GT.

Allen, perhaps you were thinking of the 302-4V?
