Question about Cars & Trucks
1 have a 1969 gto with the original 400 ci 335 hp engine with a 4& speed. It sounds perfect I'm neutral, regardless of rpm but under load there is a noise that sounds like a lifter. As the engine warms up the noise pretty much goes away. I have no idea how many miles are on the engines.
Some ticking noise is normal especially with older engines that use hydraulic lifters. The valve lash may need to be checked and you could replace the lifters but as you can tell since it only happens when it is cold, the expansion due to heat is enough to close the gap causing the noise. Therefore it is a very close tolerance and probably not worth the time to work on.

SOURCE: grinding noise while driving.
a) a brake disc shield is too close to the disc, and it's coming into contact in the circumstances you outline
b) pebbles stuck between the disc shield and the disk
c) dried out wheel bearings
d) worn Universal Joints in the drive shafts
e) worn A/C pump
f) worn alternator
g) worn water pump
Is the noise still present above 15 miles an hour and past 1500 rpm when the clutch is disengaged (i.e. gearbox in neutral?). The answer to this question may help you to pinpoint the source. I know it's stating the obvious but the fact that you're hearing a grinding sound means it's caused by something that is moving relative to something else. Again this should help narrow down the cause.
