I tried it at the Pure Stock Muscle Car Drags. It made zero difference in my ET or MPH by removing the belt from the smog pump. On the other hand, access to the spark plugs is easier with all of it removed. I am able to pull and replace the plugs with all of it in place. The smog system doubles the amount of time it takes to change plugs.

All that being said I have it installed and functional on both of my Cougars.

I doubt it has any real notable effect on hp but its sure in my way. I plan to get rid of mine one way or the other. Anyone have a line on the plugs they used when removing the pipes from the heads. IIRC from my research the plug size is 1/2"-20 and obliviously no one repros the delete plugs.

Royce kind of spilled it and I've heard it from other sources as well. Although many removed the components for a HP boost, that was actually myth or at least so negligible it isn't worth mentioning. A few raise a good point about having less stuff in your way if you're doing a lot of tuning/tinkering.

Mine had hex head bolts in the holes. I took those out and installed these https://www.mustangsetc.com/cylinder-he ... -plugs-v8/. They aren't "correct" but at least don't call attention to themselves.

Just wanted to report back that these worked perfect. Saved me a ton of time running to hardware stores searching for the right one. I was expecting a fight getting the old smog tubes out of the heads but they came out pretty easy. These plugs worked great and I’m stoked to have all that smog crap out of my way. Now I just need to find the correct non smog alternator bracket.
