After talking to Mopar Action's Rick Ehrenberg, he told me some ideas for the flywheel for you guys that want Magnum EFI but want to keep your 833 trans....

1, sandwich the automatic flexplate between the crank and your flywheel. put the flexplate in position, then put your manual 130t flywheel over that, and bolt it down. the thin flexplate won't make any difference, and is the easiest way to do this. you then only need to cut an opening in the bellhousing for the CPS to fit through.

2, he said McLeod was talking about making a 130T flywheel for these applications and you should call them and ask if theyve done it yet.

3, take your 130T flywheel to a machine shop and have them cut the index notches into it. you should probably also take them the flexplate or the 143T flywheel so they can get it degreed exactly.

any of these will work in getting Magnum EFI into your car and keeping the factory 3 or 4 speed. Much simpler than any of us thought!

Thanks, Rick....and your awesome magazine and tech articles!

Sandwiching the flexplate wont work with a standard flywheel. Pictures are gone from the thread, but we talked about it here.

I think the easiest method is to mount the CPS up front and trigger it off either a plate on the crank pulley, or cut holes directly in the pulley.

There is a bellhousing that would allow you to run a 143T flywheel, from an early v6 Dakota with an A535. Pretty sure the only mod is you have to drill one hole to mount the A833 to it. No idea if it fits in a Duster, though. I don't really want to run a 143T flywheel, though.

Oh, and my apologies for asking a question that had already been asked (if you need a core harness). Guess I didn't read closely enough to see that it was already discussed.
