update all is good no light ... this is wow big power change mod AAA someone needs to make underdrive Pulley Kits for the 300
I put the A/C delete pulley on mine from Summit. The Smog pump is still on but not being used hose cut- off in the back. I also thought about the stang pulley delete?? Not sure if it is in the same location- never really looked. As far as the A/C delete pulley I bought - I had to make spacers & get longer bolts to mount to the new bracket to the existing A/C bracket and to fit the normal stock belt as mine would not get tight enough- you would have thought the delete pulley would be the same distance???. It really just starts cleaning the engine bay up.
