well hers the bad or not so good news
What were the 60's with each carb.
People that say the 950hp is too large likely don't realize the venturi is the same size on a 750 and 950hp. The numerical rating mean very little here. The throttle plate is 1/16 large on the 950hp, that's it. Had one 340, same cam, that I mentioned to you before that made 12 more HP with the 950hp over a 750DP and was equal in the low end.
Loose on the front end is good... as long as it's not too much (mostly an issue when going in the 9's and quicker. Keep working on the 60's and get that carb pop figured out and it will get better.
MPH probably went up because you spun the tires more.
