them war cases have fooled more then one guy.

i ilke to show off my rear ends but there are in the cars .them alum are nice to lift .i have set up one and have set up the MW big roller ball bearing pinion supports they are abit tricky to work on. the iron HRW case,s have the big caps and 5/8 cap bolts they are nice and can take much HP but very heavy

wouldn't it rot your socks !!, I went and posted on the wrong post ??

Since I just joined this site, my responses will appear to out of date as far as the person needing the reply to their question. The 9 in ford rear-end was a horse for a multiple applications. It's saving grace was it's beefy bearing race bosses and the addition of it's pilot brg on the nose of the pinion shaft. Because of these features, racers on a budget use them for good protection on failure (to an extent). The biggest detriment these faced was and is in stsock form was the centerline location of the pinion in relation to the ring gear. It's 12 degrees below the Saginaw's, Dana's, Salsbury, And other OEM suppliers. This causes the pinion gear to want to "climb" the ring gear and taking away some valuable tork when "launching" and robs a bit of rotating HP when trying to finish the run when you're on the track. I hope this helps.

I have to agree with nitro..Way back when we started with our first FC we took a look at what the other guys and the touring pros that stopped at the shop were using. There was about an even spread of Dana 60 and Fords. I made a lot of $$$ setting up Fords and fixing busted ones for these guys but I'd starved if I had to live on Dana's. So we went with the Dana and only busted one. The Dana was a bit heavier and more difficult to set up but it sure lasted longer. The Fords even with the Nodular iron case back then just came apart at the seams. Most of the guys had 2-3 spares and one or 2 in the shop. It wasn't untill Strange and MW came up with the trick cases and bearing caps that they started to stay together. Today it's just Ford. The Dana is way too heavy.

A quick note on Strange and MW.....they also offer casings with repositioned pinions for a better geometry. Gives us more choices to get it to the ground.

Here is a picture of my Narrowed Ford 9in in my 57 Belair.
This rear was built for the street with a 3link coil-over suspension.
It is a Strange Nodular center with a Daytona pinion bearing, detroit locker, and 411 gears. I run moser 35 spline axles., Ford big Drum brakes.
