    Default 350 tbi durability?

    I just spent two grand on the rebuilding of the transmission in my truck. It is a 95 c1500 with the 350. After putting this money into the truck I need it to really last. I was just wondering about the overall durability of this engine. The motor has just over 127k miles on it, the truck was well maintained, regular oil changes etc. I know this because I have the records of the truck since day one. How long should I expect this engine to last? I understand that a lot of things determine this but I was just wondering what your experiences have been with this motor. Any help would be appreciated.

    im now currently rebuilding my engine with a stand alone tbi system. the engine that is being replaced has 257k miles on it. the tbi system is a good system but riddled with small problems. if you plan to stay with the tbi platform i highly suggest switching to a stand alone system.
    94 sub 6inch lift 34inch bfg mt. massive rework project soon. the audio system hit 150.3db so now its time to rebuild and try for 155db. mudpuppy is also getting a new engine, rebuilt ifs, dual 500amp 15.1vdc alts, 5 5,000amp batts, ant the combined wattage with the new system should be close to 15,000watts. this is going to be a wild ride boy and girls.
