1958 3200 Long Bed 5.3l/Jag IFS
 

My Dad and I have been working on this for a few months now, but are just now getting beyond the rust repair and into the mechanical portion of the build. The cab was in pretty bad shape and needed front floorboards, front/rear corners, and complete steps. The bed was in reasonable shape, but the front fenders will need new lower rear corners, and inner support beams.

We have done a few of the Gen III GM motors and this one will be getting the same treatment. The last build was a 55 f100 with LS1 and Jag IFS. The jag setup worked out really well so the 58 will be getting one as well.

Last week we got the cab back on the frame and set the motor in to check clearance. Everything looks like its going to work really well with no modification to the front cab mount crossmember, and just a small hump in the trans cover plate. We also found a 3.55 Ford 8.8 and flipped it over the rear springs along with shortening the rear portion of the bed. With the rear in we were able to test fit one of the 215/85/16 tires and wheels.

Next on the list it picking up a steering rack for the jag ifs to confirm oil pan clearance, and then getting it attached to the frame. I also included some images of the F100 I mentioned and my dad 51 with a 5.3l on an S10 frame. I am always open to criticism and questions so fire away.

Welcome.
Nice project.

Thank you.

I should have some good updates once we can pick up the steering rack and move on to the subframe/motor mounting.

Re: 1958 3200 Long Bed 5.3l/Jag IFS
 

We finally found a rack and finished up the subframe install this evening. I had seen some people remove the factory front frame support. I really did not like that considering how substantial its construction is compared to the thin walled jag part. We trimmed the back lip of the factory frame support and removed and boxed the humps on each side. This allowed the jag crossmember to come far enough forward to get the hubs where they need to be.

We also put a small notch in the rear, boxed the frame around them, and relocated the bump stops.

Nice job on the install.
Kim

Re: 1958 3200 Long Bed 5.3l/Jag IFS
 

We got the motor and transmission mounts pretty much done. Just a little more work on the engine mounts to improve strength when they come out again. We pulled the cab back off to paint the repaired areas and plumb brakes/fuel. I also included an image of when we were setting the subgrame/hub position. Ride height will be a few inches lower than shown. Hopefully the 215/85/16 fits.

Your project is coming along nicely. I'm a big fan of the Gen III LS engines in my projects. It looks like you have a lot of tranny in the back - is that a 6 speed auto? If so I assume it is a Gen 4 LS in front? Can't wait to see more pictures.

Just a gen iii and 4l60e.

Re: 1958 3200 Long Bed 5.3l/Jag IFS
 

Looking real nice.

Re: 1958 3200 Long Bed 5.3l/Jag IFS
 

We were able to get the front suspension put together and finish the shock mounts. I made a springs compressor as you cant use a traditional type on the jag IFS. My dad painted the frame began plumbing the brakes. Next up will be fuel.

We got the G10 van fuel tank mounted this evening. Fuel line and pump should be here by the weekend.

Fits real nice.

Re: 1958 3200 Long Bed 5.3l/Jag IFS
 

We finished the brake lines and all of the fuel up until the frame to firewall transition. The wheels are getting paint this weekend. I also picked up some caps and brushed the outer ring.

Looking good.
That's a sweet cap.
Kim

Re: 1958 3200 Long Bed 5.3l/Jag IFS
 

I painted the wheels this morning. I think the cap looks alright on them, maybe paint the bowtie white.

Those are real nice.

Re: 1958 3200 Long Bed 5.3l/Jag IFS
 

We had two of tires mounted to double check the fender clearance in the front before purchasing the remaining three.

They clear, but hopefully the ride height comes down a good bit as we get more weight in it.

Re: 1958 3200 Long Bed 5.3l/Jag IFS
 

That's a nice looking tire/wheel set up.
Kim

Re: 1958 3200 Long Bed 5.3l/Jag IFS
 

I finished the steering and parking brake after finally finding a set of CTS manifolds. When a flanged bushing shows up I can complete the column shifter to 4l60e system.

My Dad picked up the rest of the tires,had them mounted, and also modified the spare tire mount for the new bolt pattern.

By chance the mechanical fan lines up with the factory shroud. My dads 51 uses the mech fan and its been great even with A/C. Happy it fits.

I have exhaust parts ordered so that should start once the shifter is done.

Re: 1958 3200 Long Bed 5.3l/Jag IFS
 

fuel tank looks real nice. what are you using for pump etc. ? how low does tank hang down ? did you use factory straps to mount it ?

Re: 1958 3200 Long Bed 5.3l/Jag IFS
 

I modified the G10 sending unit/pickup to work with an in tank Walbro pump that uses a slanted filter sock. The tank does hang a bit low and is pretty much even with the leaf spring bottoms. We are running a tall tire so it being at that height was not a concern. The lips sit inside the frame and we made support bars for the front and back.

Re: 1958 3200 Long Bed 5.3l/Jag IFS
 

Did you keep the stock wheel base?

Re: 1958 3200 Long Bed 5.3l/Jag IFS
 

I just picked up an xj12 sub for my 58.

Re: 1958 3200 Long Bed 5.3l/Jag IFS
 

Stock wheelbase but we shortened the bed and frame after the rear fenders.

Re: 1958 3200 Long Bed 5.3l/Jag IFS
 

How low will it be from stock height with the jag stuff mounted under the frame?

Re: 1958 3200 Long Bed 5.3l/Jag IFS
 

It's hard for me to say. I did not measure the height with the beam axle and we have already removed a coil from the jag springs.

Re: 1958 3200 Long Bed 5.3l/Jag IFS
 

We decided to go ahead and paint the interior. It was the first time I have done a larger scale paint project so it took longer than expected. It is not perfect, but I am happy for a first go at it. The color is subaru ice silver. I wanted something with a bit more black than the factory silver and I think it works. I also went ahead and used some black epoxy on the fender liners, and will be doing the same to the firewall once we figure out what holes need to be filled.

I finished the exhaust with 2.5" mandrel bends and 22" magnaflow mufflers. I wish it could be symmetrically spaced, but just does not make sense with the trans servo and driveshaft angle for the offset diff on the ford 8.8. I may add a crossover if there is alot of rasp once its running.

Outstanding job on the rims.

Re: 1958 3200 Long Bed 5.3l/Jag IFS
 

Thanks

I helped my dad with the weather stripping on the doors this evening. He is going to install the seals, glass, lock/glass mechanisms this week. I need to get the transmission rebuilt so it and the motor can go back in one last time.

Re: 1958 3200 Long Bed 5.3l/Jag IFS
 

The transmission came back from getting rebuilt so we began the final powertrain install. My dad also finished building out the doors. The cab should be going on next week some time so we can begin the wiring.

Good looking project!
Nice to see that there are more people uses Jag stuff!

I welded in the O2 bungs and finished painting the exhaust this evening. It is now back on the chassis for the final time.
