gonna install one in my sbc super/pro car w/trans break. i can aquire a factory iron senter section that has the extra reinforsement ribs on it. is that going to get the job done? can't afford a new one from the aftermarket. thankyou for any input...

Make sure you inspect the area around the rear pinion support bearing to make sure no one has ground this area for gear clearence. If that's OK you will be fine I have a freind that's had one in his car for over 10 years a 9 second car with brake. Joe

thankyou. i'm pretty sure it's an unmolested unit with factory 3'55 gears....but i'll still check for what u suggested. upon dissassembly i can dry mag test it too...

Make sure it is nodular iron. Except for very early ones, they will have a big N in a square recess between ribs, just above the pinion support hole (visible from the outside).

If it's not the nodular, then check the place Joe told ya about. Look for a crack, if none keep an eye on it during winter maintenance. Trans-break's are hard on stock 9" rears.

in the long run is it better then to just save and spring for an aftermarket unit? i don't want to chance damaging the mosier housing...

Not all ribbed center sections are nodular. The early WAR casings were double ribbed but were not nodular and are the weakest of all casings. They are called WAR casings because the paert number starts with WAR. Stay away from those. They are weaker than the regular one ribb grey iron cases.

The Nodular cases were double ribbed and some (not all) will have an N in the center over the pinion. You have to do some research on the web and get the part numbers so you"ll know if one that you are interested in is nodular or not. Some had the N in the center but the caps did not meaning that it had non nodular caps. Try to find one that you know is nodular and the caps also have the small n on them.

You might look into an aftermarket case on ebay cause the factory N casess are sometimes priced higher than an aftermarket case. George

Just bring it over to Richard's and hell weld you a brace.lol Claude

Early 1964 T-Bolt cases were nodular without the N and had nodular cap without a small n on each cap most mid year till about 1978 had nodular caps toward the end of production early 1980 when the Flat Rock Casting Plant closed they regular gray Iron.

HRW is reportedly the strongest nodular case, at $329 iirc it is cheap insurance. I got one from Quick Performance several years ago.
