Just thought i would start showing some of my work on my 72 early bronco. I have been working on this for about 4 months now. I am using a 4bt out of a grumman bread van, and wanted to run an overdrive without electronics so I went with a 700r4 from TCI their 4x4 maximizer tranny for the 6.2 diesel and matching converter, This may have been a bad choice in some peoples eyes and may soon be known in mine as well. I am also going to run the np205 transfercase ford setup. plans for the 4bt I intially wanted to rebuild it but funds cut me off, it ran good in the breadvan so I think it will be alright. I do have the new gov spring to raise the rpm up to 3600 i believe.Thus far I have removed all old engine trans t-case ect from bronco. I went with a 2 inch body lift to help me with the tall 4bt, soon i started notching the frame for the starter and crank pulley. Moved on to motor mounts and then cutting the oil pan and moving the sump towards the passenger side almost 2 inches. Thanks to those brave souls on this site who I got the idea from. I am currently waiting on the transmission to get back from the trans shop I had to have a new shorter rear output shaft put in from advanced adapters to couple the gm to ford t-case. I am going to try and post pics but am new to forum posting so we will see what happens.

Nice and simple looking so far, hope it all works out well. Didn't like the idea of using a 5 speed? Love the oilpan, wow, looks like a gorrilla job; ugly but strong :). Are you anywhere near Branson, MO? I live about 35 miles from there.

Does the Bronco have a manual steering box? Looks like it from here, just wondering.

yeah the oil pan was along day.... i could have cleaned it up but just didnt feel like at the time if and when i go to rebuild the 4bt i may clean it up then. It has the power steering gear box just no lines hooked up. I am originally about an hour NE of branson but currently reside in KC MO.

Lookin very good. I love early Broncos and I love 4bts so its a win win for me!!!

I don't think you need to rebuild that motor. I have a friend with 500,000+ miles on his 6BT and it still runs like a champ and he's not easy on it! I had to change the head gasket on my 4BT when I got it (leaking water from the back water jacket) and you could see all the hatching in the cylinder walls plain as day. Looked like a brand new motor inside. I also read a thread on the DTR about a guy with over 500,000 miles on his 6BT, he blew a head gasket from pushing too much boost, any way he had pics of the cylinders with the head off and lo-and-behold there was still cross hatching in there!!!! Half a million miles and hardly any wear!

Just my $.02 we'll see how long my 4BT last, only got 9k miles on the swap so far.
