let me go ahead and get this out of the way... i know someone might tell me that what i need is on another thread but i have looked and seen some good threads but not what im looking for. i have a 1998 formula with the whole drive train and i want to put the ls1 in my 1998 5.7 vortec silverado and was wondering how much of a pain and how much time i am looking at and along with all of that what other modifications am i going to have to do to the lines i.e. tranny, oil ect. would i also be able to use stuff out of the formula like throttal cable and other things of that nature? any and all help would be greatly apreciated.
