a833od worth the swap? 72 duster
Hey I have searched but not come up with an answer that really made me feel comfortable about it yet.
There is a guy I know that want's to sell me an a833od aluminum case out of a feather duster. He will throw in a lakewood bell housing, the clutch, linkage, and everything else I would need to swap from the 727 that was going to go behind this 360 in a 72 duster. I have learned that the 4th (od gear) is not very strong and cannot take abuse. What I am wondering is if in a drag situation if I will ever reach 4th? I am not only considering this for fuel reasons, but because it is the only 4 speed I can come across. Gear ratios are going to be stock, which means I don't yet know what they are. I am in the middle of a rear swap from a 74 bb pattern dart. So will this bolt up, will it hold up to mild power, is it even worth my time? I don't know what questions to ask, so if there is something else I need to know, please tell me. thanks Jay - the man with all the questions and no clue what he's talking about |

Whether or not you will hit OD in the quarter depends on gear ratio, tire size, and engine power. I'm guessing you won't. Also, what do you consider to be "mild power?"

IIRC, the ratios for the overdrive top box are quite wide, probably really unsuited to dragging anyway... and with wide ratios like that, you'd probably not hit top gear if first gear was optimised with the rear axle ratio you're running.
And, of course, there are wide gaps in the ratios... I was hoping to get one that was on ebay the other day, but it got too dear. I think one of these overdrive boxes would be ideal for my camper, which is going to run a fairly stock 318. |

Although an auto is more consistant, or faster, driving stick is just plain fun. I don't plan to drive an automatic ever again.
Well it doesn't really matter right now, because the trans looks to be a 3 speed manual. it only has 2 shift levers, one on each side. That would mean only 4 total gears, right? 1-3 and Reverse. I really don't know anything about these though, so I could still be wrong. So It looks like the 727 will be the tranny that is put in when the engine is dropped into the duster. Unless I don't know how to identify a 4 speed I guess this will be auto for a while anyway. I don't know, maybe when my girlfriend drives it, she will really like the ratchet shifter and not care about it being auto. I don't know. Anyway, Thanks a lot. Jay Stone |

It's something you gotta want to have and take the pain and time to do it.
The O.D. tranny is weaker. The final drive is not where it used to be. They moved it to 3rd and 3rd to 4th. Thats why theres that one flipped down lever. Also remember that it no calulates to the OD ratio times the rear gear to come up with the new final drive ratio. If you allready have 2.76's.......Think. Also, if the tranny has 2 and only 2 levers, it's a 3spd. Had one, been there got ride of it. |
