[V8] timing belts

[Ron Wainwright]

Why was the 4.2 revised to 75K instead of the 60K?

 & Roger, I've all ways wanted to meet up with you. Were not that far away from each other.
 I'd let you take my 5sp for a ride. Which has been dubbed "Black Betty" Mine might not be your cup of tea though. 5sp 4.2 with race car suspension & more stopping power than I know what to do with :-)

 A Black on Tav popped up in Syaracuse, NY for cheap $$$$$ :-)
