Re: Anybody have a 5.7 TBI in your truck?
I have a tbi 5.7 in my 70 but im running the 4l80e. Its really not that big of a pain to swap over since you already have everthing from the donor truck. You will need to retain the sensors for the cooling, ignition, and injection that are already in your donor and you will need an o2 sensor but you only need one not two like originally. I had to have my chip reprogrammed to have the security lock taken out so it would run and while they were in there they did some tuning, only ran about $150. Other than that they only thing I would inquire about is the digital ratio adapter controler for the trans. not sure if its needed for the 700r but it was recomended for my application (helps convert the signal from the trans to the comp.) this unit can usually be found behind the glove box in most trucks its a little white box roughly the size of a pack of smokes. Good Luck on your swap.
