thanks guys

 

If you have the adj. MC from McLeod, you don't need to touch your clutch fork pivot T.

Yes, you should have it balanced. They default-balance it to what GM specs are, but we all know that there are variances in the build-line.

Mine was off a bit, but even more off was my pressure plate! So, I suggest you have him neutral balance the PP and match-balance the flywheel to your existing flywheel. I think it cost me $80 total from a guy with an electronic balancer.

 

but where do i go to get it doen??

 

Any engine rebuild place should have the equipment.

 

i am assuming that the stock FW was balanced to my lt1 when the car was built????

 

Right.

 

You should have a counterweight shipped with the Street Twin. It bolts onto the back of the flywheel and can be installed merely by pulling off your inspection cover.

On my car I just put everything on without the counterweight, but when I started up the car the engine shook like crazy starting at 3000 rpm, and after 3800 I was afraid to push it further... it was that bad.

Anyways after putting the counterweight on everything was fine... engine rev's over 5K and all you feel is the rumble of the exhaust

Good luck.
