Converter- 67 273/904

In my wife’s ‘67 Cúda, the 904 has the earlier lower count spline. I can’t remember right now what it was. A new converter with the earlier lower spline count isn’t possible. I looked around a lot.

What I did do was go to my local race converter builder
( ProTorque | High Performance Drag Racing Torque Converter

Your location says “La” which is Alabama IIRC for abbreviations?
Isn’t PTC near you? The PTC owner is a MoPar guy to boot.

LA. - Louisiana. But yes I am about 2 hours from PTC, and Kenny Ford of PTC has been to our shop before to help with our race transmissions.

I did a "stall" check the stock converter with the new power disk brakes, and it seemed to be quite low to me, like 1600-1800.

But before I called anyone, I was checking to see if I needed to remove the trans first to see.what I have, which seems to be the case.

Thank you

the early 904's had a smaller input with 18 splines and the hub for the torque converter was smaller as well. so the converter is specific to 67 and down units. fwiw the 68 and later have 27 splines, so at least you'll know what not to look for.

the market for high performance/high stall early converters is quite small, so it's highly unlikely to find anything off the shelf that'll be a correct match for your particular set up-- although you *might* find something close.

most have theirs rebuilt to spec locally or have a company build one out for them. PTC and pro torque are highly regarded as is PACT Performance Automotive Transmission Center

at any rate, i'd 100% grab the numbers off the pan rail and verify what you have before ordering up parts.

Thanks! I recalled hearing the was a difference in the early models. I appreciate your information as far as the years/size! I was mentally hoping I could just order parts, but didn't figure it would be that easy! Lol
