If your replying to my response I'll be nice I've probably done more HOT RODDING than most people on this siteWhatever happened to real hot rodding? Yeah, just give up. That's the answer.

would a Dakota 4.7 with manual work its 2003 I thinkIf you want to keep the original efi the only real option is to use a Bellhousing and flywheel from a manual trans equipped Dakota or Ram. The Dakota was offered with an AX15 5 speed trans behind a 3.9 v6 and the Ram had the nv3500/4500 5 speeds. It is possible to find the stuff on eBay occasionally if this is the route you want to go.
what's benefits of 904/727 verse stock 2wd drive truck trans ? are they smaller?If you want to keep the EFI and the manual trans, you will need an aftermarket flywheel. The flywheel has the crank tone ring notches the PCM uses to know the crank rotation and the stock Magnum flywheel is too large for a car bellhousing. I know of one guy that had one turned down to fit the car starter ring, but seems hit and miss as to getting a shop to do this.
You will also need a different bellhousing to bolt up to your 3 speed. This bellhousing will require a notch to be added for the crank position sensor as well.
In the end, it might be easier all around to find a small block 904/727 and use that if all you want is a cruiser. Unless you really want to use a stick.
I'm using an AX15 in my car behind a 5.2L with stock injection. It's been fine, but did require substantial tunnel mods. The torsion bar cross member had to be opened up and the sheetmetal redone.

My 5.9 was drilled for a pilot bearing.On top of the other problems, "duster george", was this an automatic or stick originally? My old gas 5.9 2500 HAD NO PILOT DRILLING with an automatic. You would have to either have the crank machined for a pilot, or hand drill a clearance hole for the pilot shaft, then use the large diameter pilot bearing/ fits in the pilot hole.
There has GOT to be a way to trigger that thing, even if you have to build your own trigger wheel, either at the front or rear of engine.
So far as balance, don't know. Surely the aftermarket makes 5.9 flywheels for pass. car bells. (130? tooth)
what bellhousing and trans u useMy 5.9 was drilled for a pilot bearing.
McLeod sells a 130 tooth flywheel that takes a bolt on weight for the mag balance.
As far a FI not sure, I ran a carb on mine.
I have done it twice.what bellhousing and trans u use

I don’t know why.Why are some drilled and some not? Is it only Magnums that were installed at the factory with a manual transmission that are drilled? How about Mopar crate engines?
$$$$$!!I think American Powertrain still makes a flywheel that will work with the ignition trigger. Part number FWCH-10004CS. Then it’s a small cut/notch in the bellhousing and mount the trigger. This was for a 4 speed.....the cost of the flywheel with my laziness lead me to put a carburetor on.....Good luck with your build!!!!!
