Like everyone said, you should look at a ford 9" or a Chevy 12-bolt. The 9-inch is cheaper to build strong enough to hold up to the power you have. But if you can't handle the thought of Ford putting your Chevy horses to the pavement, then its time for 12 bolt. I agree Moser is nice stuff, Also nice, but even more expensive, is Mark Willams. Both showed up with giant displays at this weekends NHRA event at Englishtown. Iím going with Mark Williamsís stuff Öbecause my drag racing friends say itís the best. I donít have the Hp you do, but Iíll be using a stock Chevy 12-bolt, and the following Mark Williams stuff: 33-spline axles, housing ends, and bearing caps according to the Mark Williams rep, this should easily be good for 10ísÖwhich is faster than Iíll ever go.
