9 inch

I have a big block (approx 600 hp) with a Doug Nash 5 speed in my 86 Monte SS and I put a ford 9 inch in it.Mine has the 28 spline axles and it has been in for 3 years now with no problems.Also has bigger brakes on it.I dont race it,but I sure do like to stand on it every now and then.

The reason nobody can tell you if a Currie rearend will hold up is that you haven't provided any info regarding what parts Currie is expected to use. Currie can provide rearends that will range from stock to handling 2000+ hp. Why not tell Currie what you have and what you intend to do with it and let him decide what will work based on logical input rather than having people guessing what components will be used?

I suspect that 3000 dollars is more then enough to set up a rear for that small block.

All I can say is, if you keep standing on those 28 spline axles, the're going to put you some place you won't want to be. 600 hp is too much for those axles. JMHO.....GlennK

The way the question is asked there is no real answer. Yes, Currie makes a rear end that will hold that power. The Detroit Locker will handle it no problem. You will probably want 31 spline axles. You never said what the car was used for or what kind of tires you are running, that makes all the difference in the world. If you are runing basic street radial, you can keep your stock GM 28 spline rear end, because you will never put enough stress on it to hurt it with regular street tires.

I have a blown 388 and I am running a 9" I built using Currie parts, housing, axle tubes, 9+ center section, Detroit Locker, Dutchman Axles, etc... The parts are out there to make a rear end more than strong enough for what you have planned.
