mine has 163k miles on it and I think shes starting to slow down. last time at the track I was only able to muster 102 mph traps. the dyno graph nose dives after 5200 rpm now, it just doesnt carry power. I think a fresh set of valvesprings would go a long way because it doesnt smoke or use oil and it still makes great low and midrange power.
