Looks like a nice clean install. Makes me wish in a way that I went with a carb for simplicities sake but I will try the TBI first since I have all the parts I need here. I should get much better gas milage.

Here's a question for any other GM swap guys: Could I change my FI fuel pump to a TBI pump from an earlier 2.5 or is it not that simple? It would be nice to keep it in the same location.

Ive heard that the early chevy TBI fuel pumps mount right into your YJ tank. I havent done it myself so i cant say first hand...

I plan on swapping to TBI, but for now im running carb. ($$$$)

Your build is looking good. What are you going to do with the power steering hoses? Do they bolt up to the saginaw pump?

This job is looking really good, way to go! Do you have any pictures of how you did your tranny mount? I am about to do a sbc swap myself.

And what you doing for your t-case shifter? It doesn't look like you have a stick on the floor.

My tranny mount pic is right about my last updates... And ill have my 4x4 shifter in tomorrow. I had to cut it up abit... If you go with a shifter like i did, get the cable one, not the solid linkage. They are about the same price... Cause damn they are expensive.

tranny mount is pictured above... 1.5x 2.5x 3/16 tube mounted into my center factory skid plate holes. With a GM 700r4 rubber mount from the tranny to the bar.

my tranny mount... Not finished but i had to make my jeep moveable so i can push it in and out of the shop... For some reason the boss thinks customers cars come first.

Yeah its good. I have driven it around the shop parking lot a bunch. I just got the tube to lengthen my front driveshaft today, so that will be done this weekend. I need to redo my rear axle spring perches as i have to much angle on the driveshaft right now. But ive been waiting on the front driveshaft to finish it up so i can make some exhaust. But everything is good. Just had a bunch of other $#!T that keeps getting in the way....

But its all back together now. To bad my 35s look so small now



Like this that the wife thought she needed over July 4th weekend. Its 12'x8' with 8' walls. A 3/4 loft and a full work bench on the one side...

Are you going to go for a two into one exhaust system or trying for duals.
I am going to use center dump ram horns from a 1966 327 350 hp ChevyII. They flow almost as good as any header out there, but I think I will go 2 into 1 to keep the low end torque.
