74 Scout ii 4.0 to amc 727

[326Firefighter]

I’m in need of advice from those who know or been there done that! I have a stock 4.0 and wanting to bolt her up to my AMC 727 torqueflite. I have searched and found information to use the 42 re automatic flex plate from 91-95 era jeeps.

Here’s the two maybe three things.
1: This is a 96 4.0 (obd2) and had a manual trans.(will my Crank position sensor from the manual work on my 42re flex plate?

2: what torque converter do I choose. Bone stock amc 727 one for a 258? I would like a slight bump in performance in this purchase.

3: any advice on placement of the cps sensor on my bellhousing. Any pictures that one of you guys have where this has been done? Links ect?
I know I can cut a nice spot in the bell housing. What I don’t know is how close the cow needs to be to read the ring thingy.

I know Hesco made one for the crank separate of the trans but 359$‍ woah

Any advice at all would be appreciated !

Hey there! It's awesome that you're diving into this project with your Scout ii. For your first question, typically the CPS from the manual transmission should work fine with the 42re flex plate. As for the torque converter, going for one meant for a 258 with a slight performance boost sounds like a solid plan. When it comes to placing the CPS sensor on the bellhousing, aiming for proximity without touching is key. Cutting a nice spot sounds like a good idea, and looking at some images online for reference can really help. Keep up the great work, and don't hesitate to reach out if you need more advice!
