Look at spending between $1600-2000. I'm hitting 450 rwhp on stock rear but don't drive it hard enough to require a stronger rear.....yet. If and when I do tear it up, i'll worry about getting another.

M6. Moser 9'' is the only way to go. I DD a locker also with mine but since you said it won't be raced much a TruTrac will be perfect for your application.

Why not just run the 10 bolt till it starts making funny noises

keep the the ten bolt...LMAO j/k if you have the coiin to drop on a new rear end definately check the sponsors here..lotta times there are group purchases and you can get them even cheaper that way..i personally put in a moser 12 bolt w/ a locker diff..but i do race my car..and drive it on the street * until i get to NY anyways* but never had a problem out of it..its taken all i am throwing at it..h/c/i/ full exhaust/ p&P tb/ *soon to come a 200 shot* and i am not even close to being worried..but IF you do get a new rear make sure you go the extra mile and get ARP studs for the axles..stockers ....well they twist under gobs of torque..

I would get a 9" with a locker. You could get by on a tru trac as well.

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. Bob

9" for sure...what are your current suspension mods? if you are in need of lcas, torque arm, driveshaft ect. I would look into a Fab9",I got mine from Midwest Chassis. Quality is great and you get pretty sweet deals on a stronger driveshaft, lcas, panhard ect. and it comes with a much better torque arm setup.
