Plan on putting a 5.9 mag in my van this weekend. I just want to make sure that the magnum flex plate will bolt up to a regular converter without issue. Im putting it in from the bottom.

Huh? The torque converter will bolt up to a regular converter?

The magnum 360 is balanced differently than the LA 360 or (internal balnce)318's so if you're asking about that then be sure you have the correctly weighted flex plate or torque converter.

Sorry the magnum flex plate to a regular converter??

Yes, the magnum weighted flex plate will bolt to the smaller wide ring gear no weight TQ bolt pattern with a little modification.

The flex plate has all even spaced bolts, so the one offset bolt will need to be egged out to fit the offset TQ.

Thanks. I didnt know that. Glad i asked

b&m used to make a specific mag to 727 flex plate as well. it got discontinued, but doesn't mean someone isn't selling one somewhere.

I dont think the magnums got a square converter bolt pattern til around 2000, and not sure all did then.
