Got a question to run by you nice folks. I have a 1977 Chrysler 400 with plained heads and a 440 bump stick. I picked up a 2900 stall converter for a steel of a price and slapped it in between the 400 and the built torqueflite. My question is, will the motor blow up? I have just learned that the 400 is externally balanced and i swapped the weighted torque converter out for the stall. Now, to fix this what is required? Do I pull the motor and take the converter to the machine shop? And if so can they balance the converter just by matching it to the old non-stall converter that I'll take along with the stall converter? Any help is appreciated!

Can't imagine Chrysler making an externally engine that depends on a transmission part fpr balancing. Most likely, the flex plate/harmonic balancer does the job. Did your torque converter have the starter ring gear affixed to it? I had a 75 400 but never had any trouble with the motor or tranny for the 175,000 miles I put on it and never looked at the setup!!!

Yeah, the "ring gear" is welded to the torque converter like all the dodges I have seen. I know chrysler did balance engines with counter weights on the convertor too but am not sure what is involved with getting this new converter balanced.
