Maybe if I watch you do it step by step, it'll give me the guts to start on a swap myself. I've been wanting to do it for years. Never get much further than pricing motors, still waiting for the right low mileage motor to pop up.

 

Got some more work done. Not like Jfritts or AmericanThunder. It takes me three months to get done what they do in a week. (OK maybe I'm not that fast)

I wanted to get the frame sand blasted, but I dont have anyone local. My compressor is not up to it. So this was with a wire wheel and some rustollium.

 

Man your slower than me lol....looks good keep at it

 

jealous! so where/how did u get the motor mounts for these 4bt's? saw jfritts install thread the other week n has got me lookin for one of these 4bt's. How about u jfritts where did u get your motor mounts? I will b installing in a 77 f150.

 

You got to make them. I'm going to mount the one ton diffs first. Then I'm going to tackle the motor mounts.

 

Yea i made my own mounts. And im about to make another set since my first ones vibrated loose. The new design should hold up better

 

Got some work done. after alot of measureing mounted the radius arm brackets. The first bolt is just 1/4". Come back later with 1/2" grade 8's.




Had a problem with the brackets not laying flat to the frame sides.



Some guys put wedge spacers in, But I just tightened the bolts and let the rubber bushings bend a little.

After I was happy with it I lowered the frame (without springs) to the bump stops. Nothing hits. At least a 1/2" or more clearence. I didnt want to cut the crossmember.



The tracbar mount was the biggest hassle. I was told that the stock mount would bolt up if you get a 04' - 07' axle. This is not the case. You have to cut the crossmember or the mount. Because the mount was so heavy duty, I trimmed the mount.



I had to trim alittle on the front to clear the bumpstop. Also, I had to mill the one hole larger.



Some more Grade 8's. Note the axcess hole in frame rail.



Another shot.



The tracbar fits, but I need to make it adjustable to center the axle in the frame. Note the TTB springs and perches. They just bolt on. The 60 bolts were too short. The TTB axle pivot bolts were the right size.

 

Looks good. Some people dont like to use the ttb springs for a solid axle. looks like the rear axle missed out on the paint lol

 

Got a painted axle ready to go in. (Sterling) But had to go back to work.

 

This is how I modified the stock Trac-bar. Cut, drilled and taped for 7/8.



The axle end of the Trac-bar goes on a downward facing balljoint. This made for bad geometry, so I pressed the balljoint out and pressed it in up.



Then I had to taper the hole in the trac-bar like a tierod flip. I had done the tierod flip on my DD, but the taper tool was too small. All in all, I spent about 200$ on tools to mod the trac-bar. But it looks good.

 

I'm seeing the chassis alone and i'm in love, you're doing a great job, i hope that paint holds fine.

 

I plan on doing a three link in the back. But i want to get it rolling quickly, so I bolted the Sterling 10.5 on the stock springs.



The spring plates came from the Superduty, but the u-bolts and blocks/wedges are from the Bronco. The axle tube is bigger in diameter, so I had to spread the u-bolt alittle.
