I have a 99 F150 XLT 5.4 Triton it has 215,000 miles and still runs like the first day. never had to crack the engine for anything but...... The time is coming soon to refresh it. new pistons,rings,block machined, heads worked all new bearings and so on. Does anyone know of a good place to get a master kit from or even a reasonably priced rotating assembly possibly stroker.
