8.75 Vs. 9" // Moser Vs. Strange

The reason I asked my questions were due to a freind of mine having a 8-3/4 in his all steel 69 Dart except the fiberglass hood that had a 500 inch Indy headed big roller cammed etc.... You get the picture. He wasn't fooling around with his street ride.

The car was heavy. The car ran into the 9's. How deep I forget. The 8-3/4 did break. The big enemy was weight. High rpm launches don't help with slicks but this is where he was at. The rear was unbraced with street gears, not pro gears. S/S springs were used. Off set IIRC.

Should the car be lightened and the rear strengthened and the launches not track brutal all the time, the 8-3/4 will live for a long time no doubt. If the plan is more racing the car while it retains full weight, I'd look to the Ford rear.

I also kind of agree with you statement on the HEMI rep. The real misconception is the 8-3/4 behind the "Street car" is OK for the track and it is clearly NOT good behind a big block or HEMI car that is NOT Fooling around and making big horse power.
It will do gone on the street with most build ups staying in the street.
MoPars rear of choice behind the HEMI was not the 8-3/4 but the Dana for a reason.
The Ford 9 will do fine in place of the Dana.

I think your path has been cleared.
