NE NOS AC Delco vac modulator T350/T400 - The 1947 - Present Chevrolet & GMC Truck Message Board Network

**HOTFUN** · 03-10-2013, 01:49 PM

I have been searching everywhere for an original GM vacuum modulator for my turbo 400 automatic transmission in my pickup restoration. Unbelievable but I found a dealer with a case lot of nos GM all in their original boxes so I bought them all to share the extra ones with others with nos #'s GM restorations. These are the correct large GM #3027222 modulators in the original GM Delco blue color as original. It matched exactly what was on my original grease covered 66 date coded T400. More correct is that they have the vacuum port on the side so the straight piece of vac hose attaches to the steel vac line from the manifold. According to the GM parts books, 3027222 fits the turbo 400 for all GM cars/trucks from 1965 through 1977 and the turbo 350 from 1970 to 1972. Most have the original packaged "O" ring in the kit. As you can see from the GM parts book page, these would also be correct for all high performance T400 equipped Z28's, Corvettes, and Chevelle SS's, etc.

I also have "one" lone NOS black GM 3027842 that is specific to a 73-74 C10 T350 from the GM book listing info here, for the same price. Please specify clearly if you want this one.

I'm going to offer them first come first served to this listing at $60 each with paypal fee and shipping included in the lower 48.
