I would try to use the smallest crank pulley I could find and leave the other pulleys alone. The crank pulley on my Ford is only 3" in dia. Has worked great for years. Simple change that slows down all the accessory drives. Just need to figure out your new belt length.

I agree. A small crank pulley will solve water pump, alternator and P.S. over revving. I think mine is 3".

The LS is not like the gen 1 chevy and ford engines and the crank pulley is integral with the damper. As I said, find an underdrive crank pulley--usually about 20 to 30 % smaller and change the pulleys mentioned in the previous post. Do Not change the power steering pulley--
leave it alone and only change the ones mentioned.

Dean, Is there a small pulley/damper available for the LS engines?

Oops, I misread your previous post. I'm not much of a mechanic and learning this stuff as I do it. Thanks.

Jim--there are ones a bit smaller but nothing like the small ones for the 1st gen engines. We found everything was fine with one about 25-30% smaller--which is what we used in the Red FB.

You might give him the part number, or a place to buy one, if you happen to remember that.

Huh?--what?---who is that?--If only I could remember my name---

Jim, If I knew it I would have , but, That was 'bout 15 years ago and I have a hard enough time remembering which side is up and which is down with the paddle shifters in my street car !!---
Fortunately there are more choices for parts for LS engines then there was back then and Summit prob. has all of them.

I am building a new 3rd gen MC and/or perhaps A/S car and remembering where I put the parts after taking the car apart is a b*tch! Getting older is not as fun as it was 50 years ago!!

Now where was I---
