Assuming the REV chassis is lighter than the ZX (and I would think it is) I would say the 600HO might even be quicker out of the hole than the 700. But like mxz7 said, there's no replacement for displacement in the long race.
I believe the 600HO is a lot less powerful than the 800.
600HO 116-118HP (Very good for a 600)
800(non HO) 134-136HP
I think the 600 HO driveline is more efficient than the 700 and 800 though, also it is lighter than the ZX chassis, which will lead to it being a quick sled
From what I have been able to find it works something like this. 600 HO is aprx 118 hp. They claim it is like gaining 1hp for every 7 lbs you save. The REV is 20lbs(40 lbs less then a poo) lighter then the past mxz so you pick up just about 3 hp. so now you are at 121 hp The REV with the new clutch has 12 % less rotating mass,That has to be good for geting more hp to the ground.so for what it is worth the new 600 HO should be runing with the good old mxz 700. If we are lucky might be a hair faster.. 1 Hp for every 7Lbs saved looks like Im going on a diet.... lol
