    I don't remember the torque ratings, but the HP rating for the 1996-98 Vortec 350 was 255 HP and for the 1993-95 TBI 350 it was either 200 or 205 HP. My wife's 94 Suburban is a total slug at this altitude. /forums/images/icons/mad.gif It can't keep up with traffic going west on I-70, and that's with nothing in tow. So I'd say don't even think about trying to tow the UAV behind one with the TBI 350. /forums/images/icons/frown.gif

    While we're on the subject, does anyone know the ratings for a Vortec 305?

    I know the 454's.

    The TBI 454 was 230HP 380TQ
    The 454SS tbi was 250HP 395TQ
    The Vortec454 was 290HP 410TQ
    Vortec 350 was 255HP 330TQ
    I think the tbi 350 was 230 and 310 but not sure about that one /forums/images/icons/tongue.gif

    Also,

    I had a 93 K2500 with the tbi454. It was good on power. I could tow my Jimmy at 80mph on the highway with no problem. I wouldnt always go that fast, but it could do it easily.

    John
