You will need a new fan shroud, fuel lines, radiator hoses, air intake, and maybe transmission dipstick. The driveshaft may have to be cut and balanced. You can get a PCM from Allen Nelson. Get AS MUCH AS POSSIBLE from the donor. Am I missing anything else guys?Quote:

THE KIND THAT SAY LS1TRUCK.COM,I THINK?
You can get them from Allen Nelson.
thanks alot,not to change the subject but just out of curiosity is there a list available that has all the info i might need to make the swap in a weekend
if you just want a stock harness i priced one at the dealership i work at for barely over 500, your price shouldnt be over 6 if even that at a dealership.
