I have an 01 mustang with 110,000 miles on it, currently I am saving up for a power adder(super or turbo still debating) most of them are highway miles however I know that if I put a FI on the car the block probibly won't last to much longer. I was looking at rpm-mustang at the longblocks they had or have my block worked on which would probibly be the better outcome and also what else should I look into getting or replace as well.
