    Heat riser exhaust valve

    There is no egr anymore. The 4bbl intake I put on there has no egr provision. I don’t mean to be a pain but to be clear, if I supply vaccum to ,that vaccum canister for that heat riser, it pulls the heat riser valve open?

    Heat riser exhaust valve

    So vaccum closes it. Alright. I can’t see or find how that valve looks with the flapper open . The reason I ask is, all the vaccum lines for all the emissions and such except vaccum advance was removed and I’ve been wondering if part of my rough idling could be partly caused by that

    Heat riser exhaust valve

    The heater riser valve on the outlet of the passenger side manifold, does that open if manifold vaccum is applied to it? I know it gets a vaccum source through a coolant vaccum switch, just verifying my understanding of that vaccum circuit.

    Truck is a 1980 c10. So, I could connect that to a switch controlling the hot to test if lock up works?

    Identify that wire

    Gauge ground location

    Hey all. Working on my 1980 c10 and I have intermittent not working issue with the volts/water temp/oil pressure gauges. Fuel gauge does work. I’d like to check the ground but not sure where the darn thing is. I’ve already replaced the ground strap from cab to engine block, battery to block...

    Proper throttle/kick down bracket

    Hello everyone, I have a 1980 c10 with a 305/th350c combo. It was originally a duel jet 2bbl setup but I have converted it to a factory quadrajet intake and carb. After swapping the w-jet on, I found that the throttle/lockdown cable bracket would no longer work so I went online and found a used...
