Question about a trans I have.

Confused about the rear timing hole? The majority of the RV 727s had a timing hole cut into the top of the bellhousing and timing marks on the original converter.

As for anything HD in either of the transmissions, probably the only thing in both, that would be considered "HD" would be a factory 4 pinion front planetary. You should be fine at that power level with that planetary, and a trans-brake, unless the car is going to be freakishly heavy for some reason.

The book I am reading noted it as rear timing, but yes, it does have the hole in the bell housing. I'm putting a 12 pt cage in the car, added weight with a Dana 60, I'm hoping to be 3300 or less. I'll know a weight in the fall at some point.

Do you think a transmission you build using a Cope trans brake and obviously all the other goodies won't be more HD than the factory HD transmission? Think about that for a minute.

Yes, I thought about that & yes it will be much more heavy duty. I was looking for more information as in possible built in strength in the case like wider bushing surfaces. I'm no trans guru but now is the time to start learning more, since I need to build one.
