    washer nozzle too short for cowl hood?

    Just put a cowl hood on the '74 C20, the washer nozzle doesn't look like it will work, even if it's straightened (original nozzles point up into the cowl opening) it doesn't look like it will be long enough, anyone know where to get longer ones that will fit on the cowl hood?

    vacuum switching in '74 temp control unit with A/C

    ah, mine is nothing like that. and it's 34-year old plastic and the washer won't budge, it's very tight and I don't want to break it or it's ruined. I found a guy online who rebuilds them so I'm contacting him.

    vacuum switching in '74 temp control unit with A/C

    Anyone know how the vacuum switching in the temperature control unit is supposed to work on a '74 C20 with A/C? Problem I have is that there are two vacuum-operated doors, one under the cowl vent outside the cab on the passenger side, and one in the passenger kick panel area, and they are both...

    454 with dual tanks cutting out

    My climate control head unit seems to be leaking vacuum when set on A/C, Heater, and Defrost. My guess is someone has swapped the vacuum lines on the manifold. I need to pull the instrument panel and check it out.

    454 with dual tanks cutting out

    Float level has been checked, both bowls are correct. Only once would I say I was getting on it, the other time was just barely accelerating in town, going maybe 25 MPH. Actually happened again yesterday. Wasn't accelerating, actually slightly decelerating, in town, going only 20 MPH. Bother of...

    454 with dual tanks cutting out

    I just checked ignition voltage and it's good, 12+ volts right off the fuse block IGN source, so that's not it. The second time I was accelerating lightly pulling away from a stop in town, first time was accelerating heavy. In fact it's possible both times I was just letting up when it...

    454 with dual tanks cutting out

    Also, it does have an aftermarket HEI installed by a speed shop when they upgraded heads & cam, and they made one electrical mistake by hooking a column tach up to battery 12V and it drained the battery, so now I'm wondering if the HEI was hooked up to the old resistor wire feeding the factory...

    454 with dual tanks cutting out

    My '74 C20 has been dying on me out of the blue. Once while getting on it pulling out on a 4-lane while pulling a trailer, about 5 seconds into it, maybe 55-60 MPH. Second time in town pulling away from a stop, going maybe 25 MPH. It just suddenly and completely dies. Both times I pull over and...

    Dig it. I'm a Pontiac guy with two '70 GTOs (one with a 455) and two squares. But my mind froze at the Chevy-orange-painted Pontiac motor. Sorry, but that's sacrilege! http://www.pontiacpower.org/enginecolor.htm
