1.)How much power will a 33 spline moser axel and spool handle, are should I step up to 35 spline... set up: lsx 440, 300 shot of spray, power glide..

2.)and does a moser 12bolt come with c clip elims?

 

If I were you I would consider the Moser M9 with either a locker or a spool with 35 spline axles. My '99 Camaro with the M9, 370 gears, powerglide and M/T drag radials has done 1.29 60 ft times. Here is a link to the M9, which is the same weight as the 10 bolt. http://www.exoticperformanceplus.com...html?item=1324
I would get it with the backbrace and lca brackets.

Put a 12 bolt into a early Chevelle, Nova, Camaro, etc and you can beat the crap out of it, and not hurt anything. Put one into one of our cars with a torque arm, make a couple 4000 to 5000 dragstrip launches, and I can just about guarantee you'll pick up gear noise. If it is a drag only car, you'll never know or care about the gear noise. Drive your car home from the track, and the noise will drive you nuts. I feel the torque arm stresses the 12 bolt housing, causing distortion. We have never seen this happen with the 9 inch housing.

Exotic Performance Plus strongly recommends the Moser nine inch. This rear is even tougher than the Moser 12 bolt, and the horsepower of the late model F Body cars keeps escalating every year, which requires a very strong rear. With the recent introduction of the 6.2L GM aluminum block and the excellent flowing 6.2 litre heads, the horsepower of these cars is going to just keep climbing at a very fast pace.The nine inch will handle the power, plus we prefer the way the torque arm is bolted to the nine inch in the same way the oem rear-end is attached. (This is the only good thing about the stock 10 bolt...) The Moser 12 bolt uses four short bolts to attach the torque arm, and they have a habit of loosening up, even when loc-tite is used. Why the nine inch is stronger than the 12 bolt. The 9-inch has an internal rear-pinion support that also supports the gear end of the pinion to limit gear deflection under high torque loads. This seems to be the major reason why the 9 inch doesn't start whining after high rpm clutch dumps, when the 12 bolt will pick up noise.The 9-inch locates its pinion gear lower on the ring gear to improve tooth contact, than the 12 bolt does.The 9-inch has a 0.125-inch larger ring-gear diameter and internal pinion support than the 12 bolt does. This is not much of a difference, but it is worth noting.

 

thats one bad *** diff..

 

Dam good answer, And Sales person now I want to sell my 12 bolt!!!! I will sleep on it! Because it all ready has the wolf torq arm and anti rollbar, But how fast has someone gone on a 12 bolt? I will be running a Mark Williams 35 spline axles and spool, its all track and a show car very little street so wine is no problem.. mid 9's na and who knows on spray... 9" sounds good, m9 but I really dont want to start over on my rear but If I have too this will be the time before we narrow my 12 bolt..

 

To answer the original question, if I am contemplating a 33 or 35 spline axles and do not have 33 already I would just go with the 35 and be done with the job. Yes the 9" may be stronger but depends on your budget.
