    Has anyone designed a replacement computer controlled aftermaket carb for an 85 blazer yet? You would think there would be someone out there smart enough to realize,some people dont want rebuilt carbs. Does anyone know anything about it? :D You would figure instead of having to junk a perfectly good truck , they would just build the damn thing already.

    Computer controlled carb

    Yes, it's called "Throttle body fuel injection". Those computer carbs were just band-aids until they had an injection system ready to go, and those computer carbs were the temporary solution.

    try delco??

    If anyone makes a new carb,it would be AC/Delco --but you'll have to clean lots of clogged toilets to buy one..last time I looked a new Q-jet (non electric) was over 600 bucks, :eek1: and that was quite a few years ago!..even most rebuilts are not cheap... :doah: :crazy:

    Is anyone even rebuilding these things?

    I know awhile back Holley was selling rebuilt ones as "Holley II"s and IIRC, they still list them on their website.

    This is a little bit related to non CCC Q-jets, but I have a feeling that for emissions reasons, they can't build new ones. Every single application needs different stops and what not, and some of the other internals were different based on application, and with an ECM, it's not like you can just slap one in place of another and expect it to work right. At least with a non-CCC Q-jet, it's going to be close enough for most people out of the box.

    Yeah, man, i remember looking at tose when we put the motor in, and, unless they have made some changes, they wont work on my app, because of smog laws. I wish it were that easy, i would just throw one on. :thumb:

    I think thewre was one less vac line or something, it was a long time ago, but i remember it not being able to work i think. :crazy:

    To be honest with you, I'm not sure how close would be close enough on these carbs.

    Here, take a look at this chart CCC part numbers and tell me if you are comfortable with someone telling you one CCC carb is the same as all the others?

    This is the same reason that I don't claim the non-CCC Q-jet to be necessarily one size fits all. It may be "good enough", but based on application, float height, float shape, baffle shape, primary jets, primary rods, secondary rods, secondary hangar, secondary air valve tension, secondary air valve restriction, needle/inlet design differences, fuel filter differences, power piston spring tension, (and so on) are all difference I can think of off the top of my head between two applications. It's a miracle they are even "close enough" with all those differences, but they are not going to be optimum.

    With a computer looking at the primary side, the wrong settings (you're getting into MCS stops, etc now) might very well hurt performance and economy.

    What color is your electrical ? If its blue , then this is it . I can vouch for the rebuilder , mine ( non computer ) is coming up on 2 years old now , and it still works .

    A better question is, why do you need one?

    I mean, if yours is good, rebuilding them isn't much more difficult than a standard Q-jet, and essentially the same problems with them that need corrected with age.

    The mix control solenoid rarely fails, but the TPS is almost guaranteed to be bad, and can cause problems if it is. You'd want to buy that new, believe me.
