N6dlh, do you have any lift on your rig? Is there any reason the t100 pan won't work? I ask because I'm getting all the parts together for my swap and was planning on running the t100 pan but I have a 4 inch lift with the ifs. I have not heard a definite that it would work but assumed it would. I was planning to get the engine in and running right before I started the SAS.
I have a 2" body lift, with a 2" drive train lift bud built cross member and fuel tank lift. I could have lifted the engine 2" and helped a bit, but I am certain that even with the 2" the T100 pan would not clear. I will eventually lift the engine, but as long as my drive shaft angles are ok I am not worried about it. I got the pan sealed up about as good as it is going to get. I think with a 4" bracket lift it would clear fine. There is no way I was going to go that route, with that kind of money I would SAS and call it a day. I decided to go the other route since the truck is darn near flat bellied now, so I have much more ground clearance where it is needed most, since I can and do cross some fallen tree's at times. Plus when I do SAS the truck it will be that much better. Those darn 1st Gen fuel tanks and cross members hang so low!
