Great thread. I became a true Mopar guy in about '66-67. A young down the street had '65 Satellite 383 4 spd. Beautiful car, even though not a...
Hawk, 2 1/2 turns is too loose. Should be 1 1/2 to 2. I'd try 2 see how you like it. Go down to 1 3/4 if you want. 1 1/2 is lowest I've ever run.
Hawk, how many turns do you have on the front band? If 2 try 1 3/4. The 3.8 lever takes more travel of the piston to apply the band than a lower...
If you really are at 550 ish HP, there is no kit, you need a well built 727. As Hawk has demonstrated in this thread, building a HP 727 takes a...
That servo spring does seem questionable, only since I don't know what it is. It may not be a match for your valve body. Or the valve body may not...
Interesting, never heard of 8 1/4 ring gears in an 8 3/4 housing. I wonder how they did that.
The '65 post car was always my favorite, other than a '70 Cuda. My 1st drag car was a '65 Coronet post. The Ply was more attractive IMHO. Great...
That sort of makes sense, if you have a low perf front drum with less than 10 springs. IIRC the passage in the valve body that gets drilled out,...
Hawk, I'm very happy that you were successful. Building a performance 727 sure is a learning experience. I'm going to go back & look at the...
The 2-3 shift problem can be a combination of several things. Looking back at the thread, not sure what servo lever ratio you actually used. I...
Hawk, FYI, getting the park rod in place often takes a little tweaking of the output shaft. Turning the shaft slightly to allow the lug to line up...
Hawk, math is good on paper. What makes the converter work is the design of the cover (11", 10", 9", 8 3/4"), fins and stator. And the sprag...
Hope that works well for you. BTW "Stall speed" is a very relative, almost meaningless term IMHO. Good luck.
Who made the converter? The accumulator spring makes the shifts softer for standard driving car. You sure don't need it.
A 727 is not very complicated compared to a GM TH 400. For a 727 you need to look at the FSM or other books. Understand how the different...
I used the 5.0 lever for many years because it was the "recommended" lever. It takes more servo travel to apply so the clutch timing is critical....
Hawk, .036 on the rear clutch is fine. I shoot for .030. So that's good. Overall end play at .044, not sure how you measured that. I always...
Hawk, use that servo combo, see how it works, that's what I've done for many, many years. Again, it really depends on what the valve body likes....
Hawk, which springs did you put in the front servo with the 3.8 lever? It appears you have a single outer spring. Also the late model apply piston...
Probably should have said .050 to .065. A .040 is getting a little tight. I've had a box of the different solid snap rings forever. I may have got...
