transmission/clutch diagnosiis.

Here is what I had done on my car before a grinding noise appeared..rebuilt my engine,383 chevy stroker,rebuilt differential jaguar salisbury,had the doug nash 5 speed opened and checked-up,hayes iron flywheel resurfaced,replaced both the pinion and throw-out bearings and reinstalled all this. The clutch is the same centerforce I had before motor rebuilt and the clutch releasing is through a hydraulic external slave cylinder pressing on a fork coming through the side of the bellhousing (all of this is the same stuff that was on the car before motor rebuilt and ever gave me that kind of trouble).

A kind of grinding noise appeared just at initial restart after all this work done.

It sounds as when you try to engage in gears when a clutch isn't fully engaged..kind of gears mesh grinding their tips..

It doesn't do it all the time it will take place only when the motor had reached its temp. and after having had the car going back and forth on idling speed trials!

Here is how it happens just few minutes ago: I was in first gear idling ahead here in my yard no noise and everything O.K...the minute I've had pressed-in the clutch for putting in neutral and actually while shifting from first to neutral it started grinding; then having reached the neutral position and releasing the pressure on the clutch it would keep grinding..then I had to stop the engine worried to dammage something.It looks like the shifter is only partially disengaging the gears and they keep dragging,,,while testing it today it did something similar while actually disengaging from reverse...

This transmission is a "external rods" type and the shifter is a Hurst racing type. Could the cause be misadjusted shifting rods lengths?? I had to reinstall those myself but I would think I've installed them O.K. but am not 100% sure of it.

all help is appreciated,

Is that shifter a short throw shifter? Yeah check the MANUAL (there I said it) and check to make sure you are not under or overshifting.
