While driving my 85 chevy S10 Blazer I hear this constant ticking
noise........ also at around 50 miles per hour on hard acceleration I get
this rumble which sounds like it is in the tranny or something........ but
the car is driving fine otherwise with good acceleration..........

If it's unrelated to the rumble, might be the speedo. I had something like
that a couple times and it was something about how I reset the trip speedo -
some little gear didn't engage/disengage fully. Pushing in the trip knob and
giving it a twist made it go away.

Thanks - but I"m pretty sure it is more serious...... the rumble sounds
mighty loud under heavy acceleration....
