    I'm installing a 700R4 behind a big block that is in a 88 GMC with throttle body fuel injection. It originally had a TH400. There is no place on the side of the throttle body for the TV cable to hook to. Do I need to use a throttle body from a truck that origanally used a 700R4? Did GM ever put a 700R4 behind a big block with throttle body injection? Or would one from a small block work? I'm not worried about the injectors as I'm converting it over to Edelbrock's multipoint fuel injection conversion system for trucks.

    GM never put a 700R4 behind any big blocks that I know of. I'm doing a similiar swap and planning to fab up my own linkage mount on the throttle body.

    BTW, is your 454 stock? I talked to the techs at Edelbrock about their MPFI kit and they said that it is only for use on stock 454's. [​IMG]

    Actually it is not even a 454 it is a 427. You are correct about Edlebrocks kit only being for a stock 454. However someone gave me the name and # for a guy in Colorado who for $600 will take your truck and custom burn a chip for it. I called him and explained what I wanted to do and he said it would be no problem at all. He was extremely helpful and helped me pick out the correct cam and other things I would need. I'm in the process of building the motor currently. I don't have the guys number at home here but I can get it for you if you want?

    There is an adapter from what I hear that you can buy from GM. I'm going to be doing this on my rig when I swap motors and will be trying to get the right part here shortly.

    I talked with that guy too. I posted his info on here somewhere a while back. Edelbrock gave me his name. The extra $600 on top of the price of the MPFI setup made the ol' TBI look much more attractive to me. [​IMG]
