still havent swapped intakes or rebuilt the exhaust but i did build a simple bumper, added some more length to the rear bump stops, and went wheeling with the chick a few days ago
bumper brackets are from the flop shop, tubing is 1.75 .120 wall DOM that mic'd out at .140ish. eventually ill be adding a hidden winch mount and recovery points





ruffstuff 1/4-20 trick tabs


painted




still have a nice approach angle



here you can see i had hockey pucks attached to the bottom of the bumstops temporarily till i found the time to add more 2x2x.250 square tube




couple wheeling pics





only slight carnage after this trip lol

which reminds me, i picked up a 63mm bored tb from Jeff Leigh and some stroker stickers! i was going to hold off on installing it till i was ready to swap intakes, but i had to send my old one back as a core so i put it on last night. i wouldnt say the seat-of-the-pants-dyno felt much but man did it help free up the top end. the motor used to fall on its face around 4k ish (not sure cause my tach doesnt work) but now it revs to the moon! haha cant wait to swap manifolds and see more improvement
no installed pics cause it looks stock, but heres some comparison shots
old (stock) tb


dat new new

just about finished up my new exhaust and intake swap. got the wrong gasket or it would have been put together today. apparently, whoever built this motor used a renix block and a HO head.. anyways, exhaust is now entirely 2.5" form the collector back. i kept it up high and tight around the trans and crossmember, and after that its just above the bottom of the "frame". flex pipe added to prevent the header from cracking, again. (the PO wrapped it...) i brazed the cracks the best i could and coated it with black VHT. flowmaster super 44 replaced the TINY cherry bomb i had before lol stole the idea for the bed exit from a member on comanche club. intake has been gasket matched, injectors cleaned, new pintle caps and orings installed, bolted the 63mm tb on and capped off the ports in not using. hopefully ill get the right gasket tomorrow and have it all back together.

new oem parts for the intake swap

messy...

marking intake for gasket match


had a little accident.. took it to my buddy and had him tig weld it



done



and the exhaust. ive got the hangers done just didnt get pics. once its all back together again and running ill get better ones. also still need a tip

got the intake swap finished up and put a few hundred miles on the ol jeep. definitely woke it up some! especially on the top end. the motor would fall on its face before, but now it pulls to the redline. im gonna guess fixing the exhaust leaks helped out to. i ditched the ac/fan/idler pulley mount after i got the intake on since i wasnt using any of it. took 6 tries to get the right belt though! relocated the IAT sensor as well and i also added a flange between the muffler and flex pipe to make the exhaust system easier to remove in the future.





pulled the doors off for two reasons. number one being its summer time in az and i got no a/c! haha and secondly i plan on starting my cage build soon



went wheeling a few days ago too. got a couple pics

been a while, havent done any wheeling lately, so i ripped out the interior and sawzall!






took 16 inches out of the "frame" and cut the end of the bed off. im for sure bobbing it but may also dovetail, we'll see. last night i got the new rear crossmember and shackle hangers tacked and partially welded but didnt get pics, will tonight though

Well, that escalated quickly. Put the sawz-all down and take two steps back. 
I'm interested in seeing where this goes. What do you plan to do with the shackle mounts for the rear springs?
