    I was thinking of getting a set of these for the ol' 650 DP that's on the 302, and will be going on the 331 I will be installing whenever things in my financial world get better. I was going to install some O2 sensors in the exhaust so I could fine tune it.

    Any one here have any experiance with them?

    I have them on my old 408 drag engine. I like them an they worked well! They do take special gaskets, so get a couple extra's. Easy way to change jetting an carb was consistent on the track. I never ran on the street, drag car ran 10.40's in the quarter, I don't see a problem running street with the Percy's. Good Luck
