    Okay with projects it seems like things always change or take a diffirent path .Well it has happened here Instead of doing my 72 F-250 first, i'm doing my 1978 Bronco with a 351m first


    This is the empty shell waiting for body and paint work

    The harness i built seemed to fit perfectly so the rest of the parts i have collected over the last year for this GM TBI system are going onn the bronco . Don't worry I will still be doing the 72 F-250 it's just going to be awhile . I was able to get the throttle body mounted today on the edelbrock intake plus i got the map sensor mounted well i found a bracket that worked great so i used it , well enough babbling time for pics

    one free 5.7 throttle body mounted on trans adapt part# 2210

    had to trim bolts that hold throttle body to the adapter

    test fitting on motor

    map sensor bracket mounted

    I think it looks oh so pretty lol well still got some more things to get and the bronco needs a ton of work like rewiring the whole rig . im going to use the the wiring harness kit from speedway so i will keep you all posted

    Looks awesome!

    Are going to use spark control? If so, are you interested in some helpful tips on modifying the Ford duraspark dizzy? Also, what:


    are you using? Parts of my tune might be helpful.

    Okay its update time: I have been wondering how i was going to mount the coil and the ignition module. Then one day while i was working at the wrecking yard I saw a coil bracket out of a 97 suburban that had it's ignition module attached to the coil bracket well with a little modification i was able to mount it to the fire wall and fabbed up a piece of aluminum as a heat sink for the ignition module okay here are some pics
