Welcome to the board Andrea. Good luck with your Z. I hope your stepdad takes a look at this thread. The SUs really are worth keeping and in the end are easier to work on than the 4 barrel. Folks without experience tuning dual carbs generally think it is a very difficult thing to do, and in some cases it is, but not with the SUs. Get the ZT "Just SUs" video as suggested. It will really help and may save you money in the end.
