Installed Pedro's 4" underdrive pulley. Wow, could definitely tell a difference! I recommend it, seems to have only benefits with no downside.

I had trouble getting pulley stud out so had mechanic use air gun, he removed it with no problem. Filling down the boss is easy and does not take away it's functionality. I will keep the original pulley in case engine ever needs to be locked TDC.
