I have an 87-T with 100,000 miles on it, it presently is stock and has been all its life, I'm going to do some upgrades this winter, inj, pump,chip & k&n,. Should I replace timing chain & gears first,? If so what is good choice, I have read here that the double chain & roller could cause problems (the tensioner?). Any help would be appreciated.
