    no it wont work. If you where going to do this you would need one off of a TBI 350.

    If you use the 4.3 TBI you would need to change the injectors out and put in 350 or 454 injectors.

    just tep up to the big block 454 tb its got a bigger bore and should flow more gas, you will probably have to port the intake out though to the size of the bore, this is what i want to do on my 93 chevy 350 /forums/images/graemlins/grin.gif
