thanks for the answer I just hope when I install it everything goes smooth haha

skip the plog and go straight to headers if your going to mod more.

I would get headers, but I am only looking to to a basic 3.4 setup because I am saving up for a gto

I just got the plog and I am gonna try to install it this week. I hope I can do it haha since i have no past experience modding. Also is there a how to thread on how to install one so I can have a guide line?

not a fan of GTO's or GT Slo's, they look like foreign cars, almost like a BMW, not like a sports car, but that's just one guys opinion.

I don't know about any of you that have swapped pulleys but mine was a pain in the butt! I had the right puller/installer from "Pulley Boys" and it would of been easier to remove the snorkel and use my shop press. I measured the diameter of the shaft and the inside diameter of the removed stock pulley and the pulley was almost .0025" smaller. I've read a couple of other stories of a hard removal. I heated with a propane torch while dribbling water over the seal area of the shaft and it was still a rough removal. This totally destroys the stock pulley in the process, for what it's worth.
My S/C snorkel seal started leaking a couple weeks later and I ended up rebuilding the snorkel with upgraded seal and coupler and used ceramic bearings which supposedly run 30% cooler. The moral of my story is; it might be worth removing the snorkel to install the new pulley and upgrade the coupler while it's off.
I purchased "Pulley Boys" quick-change pulley system and I love it. You can purchase different size pulleys as you continue to mod and it only takes 20 minutes to change pulleys. The puller is $135 and you need to use it if your not using a shop press with the snorkel removed.

Ofcourse the pulley bore was smaller, its press fit. I've changed 2 on my car with no issues using zzp's puller. Maybe that pulley boys tool is crap. And ya heating the shaft would def destroy the seal.
