I personally like the Max Machine Worx Billet drive for its strength, Performance, and the service the guys provide. Probably in that order. Its just my personal preference. The drive is about $15K. As far as I know, that 26 Redline has 60 hrs on it or so and I think he went through a lower gear set once(I could be wrong). I have had mine on my boat for 67 hrs and had no problems, although I have broken them in the past, but the immediate service was outstanding. I have said before, I dont expect free service, just good service, and the guys at MMW provide that to me and my customers.
The engines run on 91 octane, but will run on 89 no problem and still make 1000hp, just being safe with the fuel
