Jeep 4.0 in 69 Barracuda

I used an external master/slave setup from a mid 90s s10. A previous owner had hacked out the tunnel with a torch for a 4 speed so I had to completely redo the tunnel and upper crossmember.

yeah with 3.73s you’re gonna need to put some 35” boggers on that barracuda!
:lol:

So I looked thru your thread, and posted. What is the measurement of the mating surface of the transmission to the firewall? I ask this as my install linds that mating surface right under the firewall metal. And I am now thinking my shifter may be located at the transmission cross member. hmm I was expecting it to be behind the cross member.

I am really interested in your transmission mount/cross member. What mount did you go with? I am doing something alittle different. There is a aftermarket part called a Stinger installed on the bumper on jeeps to prevent jeep from rolling over rear over front when coming down on steep declines. I am having a stinger made to bolt to the 2 lower transmission to engine bolts (the 2 big ones), then run under the car to the back of the transmission output. Weld tabs to make use of existing cross member mounting. This will sit just below the transmission so that any speed bumps are not bashing a hole in my transmission. For looks, I may have a driveline hoop fab'd to attach to the end of the mounting system, but we will see.

Once the car leaves this fri, I probably wont have it back for 5 to 6 weeks. First to the Fab shop for engine and transmission install. Then the same fab shop will install the ford 8.8. That work should be about 2 to 3 weeks. Then the car is towed to a jeep shop who will build a custom stand alone engine fuel management harness. It could be there for a week or 2 depending on projects ahead of me. Afterwards should end up at the exhaust shop for a factory inspired XJ exhaust. 2.25 head pipe to Cat Converter, from CC 2.5 in pipe into a flowmaster 40 series muffler (chambered), 2.5in exhaust out of muffler and over the axle and out the rear. Yes I am installing a Cat Converter. Doing so the ECU fuel management wont complain as I am making use of the O2 sensor as well. As the ECU is not being reprogrammed yet. That said, I run MagnaFlow hi flow half cat's, its about as close to NO cat converter as you can get while still making the ECU happy. And its noticeable on the skinny pedal.

Anyone who has heard a 4.0L cherokee or grand cherokee with that system knows what it sounds like. And its mean. You can bet I will have youtube video of first start.

Keep everyone posted.
