    hey whats up guys was wondering if anyone knows about the 5.7 vortec and if it is a pain in the ass to install a carb and installing a manifold. i have a 97 chevy and i just want to get rid of the computer and go a little more old school. i pretty much know what im going to do, im just wondering if anyone has any tips before i go and buy parts and get down and dirty. i plan on getting rid of the computer i dont want to deal with sensors and S^&*. this is my toy so yeah if anyone has any info and what parts i should go with give me some info thanks guys.

    The 96-99 vortecs have excellent heads and run great, stock or carbed. Edelbrock makes Performer vortec manifolds like the 7116 shown below. You will need a different fuel pump or pressure regulator for a carb. Then you need to figure out an ignition. A regular hei or msd distributor should work but Im not positive.. Also beware your emissions legal will be history, and could affect resale value.

    I would only worry about a stock vortec leaving my carbed rig in the dust!

    YEAH im not to worried about the resale this is my toy its already in process of being completly transformed hahah. my plans originaly was to install a 6.0 vortec but i know i can get alot of power out of this engine doing it right. this should still be legal to drive anywhere. but it will mostly be in the dirt. im just tired of the having to deal with sensors ect. thanks man ill keep u posted.

    You will also need a stand alone ecu for your trans. I belive you have a 4l60e which if you go carb will not know when to shift.

    I don't know. You won't have to smog it in Yuma, but you'll be in violation of Fed law.

    California has legally crushed cars with modified or missing smog equipment.

    FI works better in the whoops anyway.

    Yes, you will only have to deal with the ecm on the stock 4l60e. You could keep the 4-sp 4l60 by putting a manual valve body in it, or run the th400.

    and no speedo, but youll be ok with the TH400, and prob no guages.

    the factory FI realy work well, im not sure why you want to get rid of if?

    The factory cam in pretty tame and you can easily overcarb it

    Should be interesting

    IMHO, EFI>>>Carb. As others have said, that engine is great in stock form. Some bolt-on power adders and a tuner and you will be happy. And as someone else said, you are violating Federal emission laws by doing this, and CA isn't the only state that has crushed cars. Just because a state (or in your case, a county) does not have an inspection program does not mean that you can legally remove the equipment.
