73 swinger built 318, a998, 3:50 gears, 28" tall rear tires... 9.8:1 C/R..340 m/p cam , 4bbl, air gap intake, still has a/c not used, and power steering, went to manual disc brakes, removed the power unit.
will be rebuilding another transmission A904 1973 model.. thinking of a mild stall converter... anyone out there running one in a904? was thinking @2000rp. is a street car... with some playtime once in a wile.... any thought of what works well?, brands? everyone says 2500 rpm but maybe to high for daily driver? just want a little more flash for the cam idle...
 
No, Hughes off the shelf are historically wound tight. Plus you got 3.55 gears, your spinnin' 2500+ over 50 mph. You'll be happy with it.
 
First, STOCK Mopar converters flash a little on the high side anyway. Usually in the 1200-1500 area. The stock Mopar high stall was around 1000 RPM more.

The 340 cars had the factory high stall and were a GREAT combination. 3.55 gears are fairly mild. The 340 cam is really mild. I think it will be perfect with a tight 2500.

Don't cheap out on the converter. Converter technology has come a LONG way in the last twenty years. You can get a converter now that will be tight driving down the road to produce less heat and get decent mileage, but will flash on demand to a given RPM.

Thing is, you won't need a high flash point, because your combination doesn't require it. The 340 cam makes power from idle to 5800 or so RPM. It is a 318 so it might benefit from a tad more RPM, but don't go crazy with it.

This.Had a '67 Cuda,low compression 360. Ran a 727 with a reman"Road Runner " converter. Ran great ,with similar cam spec's, would flash /footbrake 2100-2200.It would 60' foot 1.7-1.8 times .2500 sounds about right,Hughes makes nice stuff,seen their budget stuff work.
 
tci came back with the info.... for the tci A904 BREAKAWY CONVERTR 2300RPM...
ANYONE USED THIS ONE BEFORE?
 
TCI blows dead camel balls.
 
I'm using a Hughes converter as well. Do it. Their phone techs are awesome.
Stay away from TCI. Unless you like dead camel balls like RRR said...
B&M is hit and miss.
Not sure about ACC Boss Hog's... Anyone?
 
in summit catalog shows manual valve body in add for both 727 and 904 is this true? and if so can I use a manual v/b on a a999 with lock up, I know no lock up will occur....
 
I just installed a hughes 2500 stall in my dart with a mild 360,3:55s and 26" tires.In my car it starts to flash about 2100.I would stay away from the Boss Hog,had one in my car lasted 3 yrs,crapped out Easter morning,weld cracked where the hub is welded to converter and spewed out 4 quarts of flyid in about 1 min.After driving the car with the hughes I doubt it even flashed at 1500.
 
I rarely install anything higher than 22-2500 on a car you have to drive a lot. You can pay more for something that stalls low, but flashes higher, but it doesn't sound like you want or need that. So I'd stay lower. My rule of thumb is you want to have the engine above the flash stall (always higher than brake stall) if you're in 3rd (or OD) at 50mph. Normally that means less than 2500.
If it was me, I'd stay away from TCI. They do suck. Dead camel balls.

I bought a used 904 that had a Boss Hog in it and it needed a new snout cause it had a little groove wore in it. Took it to my converter man and he cut it open for inspection. What a piece of garbage! It had so much clearance in it the thing had to slip something awful. Threw it in the garbage where it belonged

think a 2500 maybe too high for daily street use, and freeway driving? just asking...

2500 is fine if it's a good converter like a Hughes. In the old days almost all high stall converters slipped bad so 2000 was about as big as you'd want to go on the street. Nowadays they've figured out how to make converters flash stall very high rpm and not slip much. My previous converter was a PTC and built to stall 3000 behind my engine and before I installed it I was running a MP converter that stalled 2200. When I installed the PTC I could barely tell any difference in the way it drove from the MP 2200 but when I layed into it it'd stall 3000-3100 and made a big difference on how quick my car was.
