5.9 Magnum flywheel - DIY with bolt-on weight??

Thanks, very helpful.

I actually don't mind buying the part if I know I need to but there is a process in arriving there, and there is learning in getting there.

Some of this might seem stupid to the old hands but if so you have forgotten where you started out.

There's still some questions.

Is there a factory 130 tooth 360 flywheel or did the 360 cars use the truck flywheel with a truck bellhousing?

How do cast flywheels hold up to hp/rpm?

Is the 318 flywheel neutral balanced? Interesting that the Mcleod unit has a recess. I wonder if that means its not neutral without weight. Maybe there's a "neutral weight" that just takes up the space?

Again, a lot of this for me is curiosity and learning (fun). I posted with a title that should make it easy to find for others who run into this issue. I've learned a TON with the search button.
