thanks muzza. When I say "heavy" I mean the flywheel/clutch combination physically weighs a lot. The pedal was not too heavy.

The conundrum I now face is that to check clearances I need to pull it all out, and then if I determine that it is correct (or shim it as required) and put it all back together, I risk it still having a problem. The LS1 forums in the US are littered with people complaining about this clutch not releasing at high rpm.

the shift in my case gets harder and harder as the RPM increases. I have experienced crunching as low as under 3000rpm, and over 4000rpm it basically wont go into 3rd or 4th.
