    On the 76 we just bought, I know the guy I got it from swapped in the whole drive train, including the axles. My question is, on the power breaks it dosen't have a vacume booster, but instead the power steering pump feeds the power breaks. Wasn't that only on the deisel rigs?

    On the Blazers, I believe so and I think they may use it on 1 tons also. It is called Hydro boost. Supposedly it has a higher clamping force than the booster style... They use it in the diesels because diesels dont create much vacuum and cant use a booster... I think this system will also work when the vehicle is not running...

    If the brakes work good, I would leave it in there.

    SO if this is a deisel rig, I don't have to smog it.[​IMG] That is the best news I've had all day. Are there any other signs to tell me if it was a gas deisel?

    Look at the fuel gauge. Does it say "Diesel Fuel Only" or "Unleaded Fuel Only"? (Though that could have also been swapped). Check the filler neck. Does it have an unleaded restrictor? The diesels didn't have that so a diesel nozzle would fit. I think you can also tell by one of the letters in the VIN, but I don't have a book here to confirm.

    The 6.2 didn't come out until '82. The 350 Olds diesel was available from '79-'81, but I think you could only get it in a C10. If it's a '76, its a gas rig.

    The 3rd digit is the engine for '76 the codes are....
    d..250
    v..305
    l..350
    u..400
    I dont think a diesel was available yet in that year 78 being the first year of the 350 diesel and 82 being the first 6.2

    Have the VIN checked... There is either a list on here or on CHucks Chevy Trucks page: EMMETT</font color=green> -&gt; <A target="_blank" HREF=http://emmett.coloradok5.com>http://emmett.coloradok5.com
