    I have a 91 Sub with a 350 TBI motor that I would like to swap a 454 into and keep the TBI setup. Will my current systep work? Any info would be helpful.
    Thanks

    The swap is possible, but I don't think the 350TBI will work properly with the 454. Just get a carb, or look into the expensive stuff like Edelbrock's MPFI system.

    Why not get a 454TBI unit? You can llok for a junked 454TBI engine or get the BB you had you eyes on and get a 454 TBI unit from a place like <a target="_blank" href=http://www.turbocity.com>Turbo City</a> then get you a chip burned for your setup and you are ready to go broke as a result of the tremendous adrenailne rush you get when you sit at a green light with the EPA after you for serious tire smokage...[​IMG][​IMG]
