lookin good you have to clearance for the exhaust then?
I plan on puttin a 6.0 in this summer in my 86, but with carb th400, so im subscribin to this
what headers r u getting and what do u have to do to them for them to fit?
header from summit part# SUM-G9048 $153.93 they are shorty headers fit 99-04 truck requires slight mods to PASS side rail
you can cut a small chunk out of the frame so it will clear or, you can do as i am i am going to cat the header off at the flange and and add about 2 inches of pipe in to it.

Here is some of what I got done today
doesn’t look like much but removed all the old fuel lines, cleaned the frame some, bolted in the core support, got everything lined up and bolted in. Now just to wait on my wiring harness and computer.
Been a while since I been here. Done a lot to the truck, got the body put back together, drove it around some. Runs ok I just need some help from the folks here.. The exhaust on the truck is down pipe with 02 sensors and catalytic converters installed but stops there. But truck will Idle great, in neutral if you give it throttle it sounds good but if you get it ½ throttle or much over idle and completely let off the throttle the truck will die but if you come down slow it will idle, put it in drive it will pull off like normal same deal with throttle if you apply enough throttle as to pull off at a decent speed it bogs bad let off it will go back to idle.. sometimes die. Attempt to try burn out it bogs bad and will die. The fuel pump is new the one I used was recommended by other members who have done the swap.
no but i changed the throttle body and it made a huge difference. now it just is kinda high at idle, but i think the idle air control valve is bad looks like it might of been bent some. Got to figure out how to hook up the OBD2 Port i believe the orange is the ign hot wire, there are two black weirs i guess there ground? matter where they ground to truck or battery? and the purple wire is the wire for the OBD2 wire coming out of the harness. I just cant get the OBD2 code reader to read anything. ign on and both black wires tied together and hooked to good ground.
I do not know anything about this so this is what I need to know.
I got the transmission n all bolted in right. I did not have to move the cross member, it is all the way forward, here are some pictures of the drive shaft in the pictures I have it bolted into the yolk in the rear end. By judging how much is at the transmission do I need to have the drive shaft cut and shortened or does it look to yall like it will be fine? To me it looks like it would be ok but I do not remember how far it was in the old transmission.
