Out of what vehicle? 1" wider is harder to deal with than 1" narrower. Most guys go with a 9" because there is a HUGE aftermarket for all the parts. Axles are available in 40 spline, strong spools, great limiterd slip options, HUGE selection of gears and gear alloy's (drag gears are softer), ect. If you NEED a stronger rear end, the Ford is hard to beat. Strange offers a Dana 60 that is bolt-in, and a 12 bolt, too. What did your 14 bolt come out of, and where is pinion location comparede to a stock 10bolt. THe stock 10 bolt 8.5 will live a long time in a 9 second car properly built.
