Pully question I was looking into getting an underdrive pulley from SLP and I was just wondering if I should get a shop to install it or do it myself, Because I have little experience in engine work.
It's not the easiest install you could tackle.

If you already have an underdrive pulley on there, either pull it off using a 3 screw type puller, or be VERY careful and grab onto a lip of the underdrive pulley (on the f-body ASP pulley there is a ridge half way back that can be pulled on safely with a 3 arm puller). Keeping the pulley puller arms all secure and aligned, begin to tighten the bolt on the puller and crank on it until the pulley either comes loose, or hits the head of your crank bolt. If it hits the head of your crankbolt, loosen the pulley puller, unturn the bolt 1-2 turns, and re-try it again. The key when you back your crank bolt out more, you are putting MORE stress on less and less of the threads...however, towards the end of pulley removal it will come off easier and easier so the stress isn't enough to damage the crankshaft threads.
If you get the pulley as far off as it'll come without totally removing the crankbolt and the pulley is still firmly on there, give it a good tug or a tap with a rubber mallet...it should be hanging on by just a hair at this point. If you have the longer crank bolt, this won't be an issue.

yeah it all depends. tools are important to have the right ones and a lift makes it easier. i did mine at a buddies shop but would have gladly paid $80-100 for somebody to do it. i dont think you will find a shop to do it that cheap though.

Thing is, most of the work involved swapping a pulley is the same work involved swapping a cam. That's why most people do it at the same time as cam, because the stock pulley has to come off anyway. If you can overlap the labor, that is best.

It is really not that difficult. I have done it a few times but if you can find someone to do it cheap it might be worth it. Just make sure to get a new bolt when you do it and torque it to 240ft/lbs.
