i have had the max xxl3, the nova 353 modified and now i just got the rbm3 modified but i haven't tried it yet. the max and nova both awesome engines, both great bottom,mid and high, but i really can tell the difference between both, but i think the 353 pulls a little more on top with the 2652 pipe. from what i've read the rb is one of the most powerfull engine to date. and from what i've seing on track, no matter how powerfull is your engine if you can not control it the right way. so you can't go wrong with any of the engines you mentioned.
any of the three engines that i mentioned, wich i have tried, last a lot, i mean a lot.
