I have a 2.7i with a 290/290 cam and my idle is stable..
I think you may have a problem of rich/lean mixture at idle or check the idle switch is on at your trottlebody switch assembly ..one way to check is with a ohm meter or move the throttle very slowly and listen for the click.
And make sure it is on at rest position or you wont have any idle.
As for the clutch noise ....do you know if the 2.7 crank you got was from a automatic or manual car... there is a bearing at the end of that crank for the tranny shaft.
I had a similar issue and i had a crank without that bearing so it was noisy.
