header from summit part# SUM-G908 $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.

im in for this cuz if it works its the route ill attempt
great progress btw

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.

That looks about right. You have to have room for the suspension to compress. If you do a drop kit on the rear it will be sliding further into the trans.

Hello everyone. I'm new to any kind of forum. I've done engine swaps b4 but never like this. I have a 1981 silverado LB. I'm doing a 305 to 1998 ls1/4l60e convert.This Is my truck .I think i've pretty much narrowed down the items i need for the switch however, I'm stumped on a few things. What about the gas pedal. Would I need the pedal from the donor vehical? I read that I would have to make a few linkage mods. A little clarity on this would be greatly appreciated. Much thnx for reading...
