    It would be an awful headache to convert your truck to a carburetor; and it also would make it illegal, which means it would never be able to pass a smog test. The computer and transmission would not work right, and there would be many other problems. The fuel pump used on fuel injected vehicles produces way too much pressure for a carburetor. You would have to remove or disconnect that pump, and replace it with an electric pump intended for carbureted applications.
     
    GM Performance parts makes a 350 truck crate engine for 95 Chevy pickups which has a 9.4:1 compression ratio, 200HP and 300 ft-lbs of torque. It has a high volume oil pump and will bolt right into your truck. It does not come with a fuel, ignition, or exhaust system; so you'd need to use these parts from your old motor. Summit Racing sells this motor under part # NAL-12568758 for $1,769.95 plus truck freight shipping.
     
    If you want more power, I would suggest using a higher powered GM crate engine. Summit also sells a 290HP 350 long block, with 326 ft-lbs of torque, and 4 bolt mains. It has part # NAL-12499529, and sells for $1,924.95 plus truck freight.
     
    For even more power, Summit sells a GM Performance parts 330HP 350 long block, with 380 ft-lbs of torque, and 4 bolt mains. It has part # NAL-12486041, and sells for $2,679.95 plus truck freight.
     
    If you decided to stay with your TBI injection; no modifications would be needed when used on the 200HP truck crate engine; but for use on one of the two higher powered engines, you would either need to use a high performance chip in the computer; or install a piggy back fuel controller, in order to supply the air fuel mixture needed by the more powerful engine.
