We're not finished yet but I can safely say that the Indy cross ram picked up a ton of power over the MP cross ram. At least 75 hp increase, maybe more. We need to do some more tuning and I need to stare at the dyno sheets for a bit to understand just what all we saw today.

The really interesting thing to me was that the cross ram ran just fine with out of the box jetting on the Eddy carbs. There was a little variation from cylinder to cylinder but not bad. The Indy ram wanted the carbs to be jetted up a bit. I went up 3 sizes and that wasn't enough. Probably need to go up another 3 or 4 jets sizes to get it into the ballpark. And it needs some cross jetting to be really dialed in but I don't think we'll spend the time doing that.
