Try this . While in neutral and you are hearing the "noise" , mash the clutch pedal down  and hold it there (don't move the shift lever) . If the "noise" goes away and returns when you let the clutch pedal back out you could have a Main shaft bearing inside the tranny thats bad.  Again do not move the shift lever. Always have it in neutral and the car not moving.

Not really .  Test it like I said please. When you are driving  there are several other bearings that come into play and that makes its harder to tell which one it is. You don't have to move the car one inch to tell which one it is. So do like I tell you.  One repair is fairly reasonable and one is high dollar if it is the pinion bearing or the ring and pinion gears.  :?

It burrs  vrrrr  with the clutch in  it vrrrs with the clutch in

well it wrrs whether the clutch is in or out.   sitting still.  it does not wrrr idleing,  just when I rev

I think I'll pull the fan pully off and see if the noise goes away

I also have not  fastened the 4th trany-engine bolt yet that is near the oil cooler,  It was a bugger since it was getting dark when we threw the engine in.

 Mosquitoes are bad around here and they like how i taste,  I'm out of bug spray,  Bo and gas does not seem to deter em

I got some bug spray,  so I braved the great out doors and  took off the fan pulley belt.   Stupie would not start,  Oh, well,  May out of gas.   I need to fix the gas gauge some day.

    Started  checking things.  The carb manifold sure has alot of wiggle in it.  The manifold to 3 and 4 is loose.   Great,  It sure is hard to get those bolts tight.  Now they are tight,  I thing the vrrr sound was a giant intake leak.   I messed around with stuff,  and got that 4th bolt that holds the transmission  in.  Stupie sounds different  and starting to idle. sort of..... Hurray.   SC
