Yep, hard to beat a Holley for WOT power production. Not sure if that particular model has the 'dogleg' annular discharge venturis that vaporize the fuel better.
But that particular design was used very early on by MC in these carbs....basically designing a foolproof, dependable mileage carb for medium sized I6s that still made good power when requested.
Don't get me wrong, I love Holleys for making power. I ran a 700DP on a Boss 351 for years. Great carb for tuning. But they do have more parts & seals that can fail or leak.
For a Jeep carb that's bone simple & gets great mileage right from the get go, it's difficult to beat an MC, imho.
