Just wondering how it might hold up, must be some "over-engineering" from the factory in these smaller Torqueflites.
ati make a less expensive alternative to the 24 spring kit....looks just like the stock spring but is wound the opposite direction...20 bucks
I guess Mopar wasted a lot of money engineering the 727-A.
So if you are looking to put a 904 behind a 340-360 HP motor, you should first have the trans built with modern parts. Yes ?
Are you only referring to clutch pack clearances. A friend of mine locally runs a 69 dart 11:20,s with Griner brake which he claims has low band apply. Launches wheels up every pass. He just destroyed his roller clutch. Cannot get the drum out of the case. Claims to have an aftermarket reverse servo. Drum,band,and servo all in good working order. Anyone care to explain this failure. He thinks he needs the new better aftermarket roller clutch. He says the trans is late 1960,s model. This motor is a 360 cubic inch with j heads.Yes and no. Back when they were made the friction materials weren't as good as today's stock replacement clutch plates and bands. Also given the fact that the factory tolerances were all over the board made the design of the 727 the fool proof one to go too behind a high perf engine. Were lucky today to have the benefit of much better friction materials and have figured out what clearances work best so we can make a 904 live behind something making twice the power it would originally handle.
the clutch plate clearances and the end play settingAre you only referring to clutch pack clearances.
That is one of the craziest statements I have ever read here. It’s gotta be satire! Otherwise, how do you figure that! The 727 came out a good bit before the 904 and has won awards on a few fronts.I guess Mopar wasted a lot of money engineering the 727-A. Here is some reading to educate....

Read below.While we are on this topic, what flexplate are you all using with this 904 setup? Factory or aftermarket? Part number? Thank you.
THIS ^^^^^^^^^^^I run SFI flex plates, but my application is race only. When I had street cars, I ran OEM flex plates but they were thoroughly inspected for cracking.
