so when you do "pullies," how many do you actually replace?

I only replaced my crank pulley... The BIG one...
Some people replace the alt. pulley as well.

Overdrive Alternator Pulley - Recommended for automatic cars to help bring alternator speeds back to near stock levels without sacrificing too much horsepower. Extremely important for vehicles with high accessory drag such as cars with lots of stereo modifications.

Recently installed the SLP damper/pulley. I bought a longer bolt of 130mm where the stock bolt is I think 113mm long. Washered up as I went and fought it on. I couldn't get the stock bolt to move the damper once I had enough threads for it to grab onto inside the crank snout. Even after removing the dried out red RTV stuff on the bottom side of the bolt flange and lubricating the flange I couldn't get the damper to move. Just got a trick from the Texas chapter to heat up the damper and it should slide on. This should work because I have used the same heating principle to get ring gears on flywheel.
Haven't driven it yet, waiting on a tool from summit to keep the crank from turning then will bring the new bolt on around to the required 140 degrees. But I have put the belts on and cranked the engine, no oil leaks and the belts stay on when I rev it up.

SLP sells the pully for $249.95 and it includes the new bolt, but you still need the new belts, (Gates #K060763 and #K040378 or equivalent. If anyone knows of a pully that it just as good and where to get it cheaper, please let us know. Thanks.
