Will a stock magnum 5.9 flexplate work with a 904 converter?

[LXguy]

Hey All

Thinking about putting a 5.9 into my Dart. I see that with the crate motors, Mopar recommends using a flexplate (P4876706) that looks exactly like the one I pulled from this 5.9.

Mopar says this flexplate lines up with Econo and Lockup converters, which appear to work with 904 and 727 trannies.

Seems like everything would be cool (other than no SFI), but I thought I'd ask if anyone knew anything different.

Thanks

Steve

id say as long as the crank pattern matches 6 or 8 bolt

I'm doing the same swap. But I'm useing the EFI flexplate/tone ring with the 904 converter. The magnums bolt pattern for the converter bolt pads are equal spaced, So I will just file the one hole to match.The LAs had one pad off set.
Since the flex plate is balanced for the magnum I'm useing a 318 converter.
Check out my thread 5.9 magnum into 73 duster. We hope to get some more work done in the next couple weeks. Good luck. OG

Thanks for the post. I'm having ultimate converter do me a converter and they said they could do equally spaced. I just didn't know if the tone ring would hit anything.

I've been watching your thread.

Thanks again

Steve
