[1157 motor head]

I have a 70 GTO convert. with A/C. it's just a 400 with auto trans.
on the front of the intake manifold is a thermostat controlled, multiple vacuum port. I looked in my assembly manual and I do not find an illustration of how to route vacuum lines.
does someone have an illustration of what color stripe is on the line and where the lines go?

thanks Jim

Has it been that long (talking to myself). I remember the '69 and the '71 having the multi-port thermo switch, but not '70. I'll look.

I think you are looking for the engine vacuum lines, but this may help eliminate some
