/6 conv. on V8 904 to advance stall ??

[lilredridinghoo]

Hi guys, while cleaning up some stuff in my garage, i got an mind flashing idea: is it possible to mount a /6 torque converter to a V8 904 tranny, and if it works will it give me a higher stall/quicker launch. and if it works how long will it last with about 300 HP

I had no idea that you could use a slant 6 torque converter in place of a 318/904 unit...

I might need just a little more "oomph" out of my converter with the cam, heads and compression I'm using...Right now I have the stock 318/904 converter...So this sounds like a good idea...Would like to know more though...

Hey James,you,ll want a converter to match your cam and gears for max performance.

lol...I know!! I'm being cheap and don't really wanna buy a new one though...They like 3-400 bucks... :l

I think all I need is just a touch more, like 4-500 more stall...It is an edelbrock RPM cam though. 234/244 dur.@ .050 488/510 lift and I have 355 gears...ALMOST 9:1 compression, not quite though. lol What do u think I'd need for converter?

I'm just looking for a street setup, nothin serious for track duty. Would like it to not be a dog though...

just wanna push this thread up again...

next question will be: how to decide between a slant six conv. and an normal V8 conv.

heard that sometimes the same conv.type was used for both by mamopar ??

will there be a list or somewhat out there - to check part numbers and there use ??

Hi Timo,

I am having the same question.
My engine is a 273 with a E-4 camshaft. Duration at 0.050" is 216° and at 0.020" 260°, RPM-Range is 2000-5500.
I will drive the engine in my 65 Valiant with a 904 transmission.
if I want to use the full power of the cam, do I have to use a performance converter, or is the /6 converter correct for this aktion?

FWIW:

The 318/904 torque converter has the same part number as the 225/904 torque converter in 1971-72. Likewise the 727 converters are the same on both engines. Unfortunately, the parts manual does not give the specs on any of the converters, only fitment.

here's the secret /6 trk converter .... used them for years when no one use 904's they will flash about 2200 behind a v8 .... i ve none this since the early 80's .... or you can call dacco transmissions they built me a nice 3200 to 3500 stall for under 3 hundred $ it drives normal it will flash 3500 range ...... an pulls like a fright train ..... another little trick is to use the back 1/2 /6 and the frt half 360 v8 5 clutches ..... the back half gives you a lower 1 st gear ratio happy motoring

Hi dartman340ta,

sounds like you know a lot about transmission.
So in my case the /6 is the right, inexpensive choice?
2200 Stall sounds good in kombination with my engine.

trail an error is all i can say an some help from friends along the way .... trans kits i get from dacco they have warehouse's all over just ck the internet the main plant is in tenn. good prices my last one i put kevlar band's in they where 25 an 45 each an a trans kit was less then a hundred i put a 3200 to 3500 stall in from them it was 297$ plus tax when every one else wanted 5 to 7 hundred an a manual valve body i got out this site for like 50$ ... i do low budget there easy to do also if you have some of the tools you need to do them ..... fishy68 on here no's them inside an out good guy .... have a nice one
