700HP/1400LBS FT of torque is a good start to why its getting boxed.

Re: Finally starting my Longhorn 4x4 conversion
 

Wow, thats crazy power. makes sense given that

Re: Finally starting my Longhorn 4x4 conversion
 

im kindah wondering if boxing the frame will cause it to crack near the crossbraces where you need to work the plating and welding around ,
wat might work is to get a second frame take both the original and the extra apart so you only have the framerails make one of those thinner cut them towart the bended part so they shut straight ontoo the other original rail and swap left to right and vice versa , cut and shut the crossmembers so they fit ontoo the inside out and thinned framerail and you still can use the original bodymounts on the outside part on the original framerails and can still fit the front suspention parts after you remount those , put the original framerails on the outside and weld them together to get a boxsection out of one piece , only the part near the front suspension needs sumting made as it bends in more than one direction

its hard to explane but basicly you make the boxplates out of one piece using the extra frame and change the crossbraces to fit and be mounted to the inside plates so they dont go through the plates to the other frame and keep the original frame as is exept for the crossbraces everything mounted on the outside of those rails need to stay at the original location and at the original width

Re: Finally starting my Longhorn 4x4 conversion
 

I highly doubt the frame will crack. It's already a pretty heavy duty frame. Plus I'll be redoing some cross members and the GN hitch will be sitting on 2"x4" 1/4" tube. I'm sure it'll be rigid as all get out. :lol: This isn't a trail truck, so I won't be trying to twist it up either.

Re: Finally starting my Longhorn 4x4 conversion
 

Of course, after I ordered mine already. Thanks buddy! :mm:

Because if I don't, I'll never hear the end of it from a couple of net thugs. :lol:

The biggest problem were their front frame horns. It was a really chitty design. They also had steering box frame area cracking issues too. It also couldn't have helped that those frames were started in the early 70's and just modified clear up until the early 90's.

Re: Finally starting my Longhorn 4x4 conversion
 

It's amazing that I've lost the little bracket that holds up the steering column against the brake pedal bracket twice during this build. Man, it'll be nice when this thing has all it's parts bolted on it. :lol:

Re: Finally starting my Longhorn 4x4 conversion
 

peer pressure...

Re: Finally starting my Longhorn 4x4 conversion
 

thats... wow. i deleted my complement cuz it wasn't big enough.

Re: Finally starting my Longhorn 4x4 conversion
 

:lol: It definitely has the fuel and air for 700hp, it just needs all the little stuff to make it fire, and put it to the ground. :waah:

Tick, tock, tick, tock. :josh:

was that my kick in the junk?

Re: Finally starting my Longhorn 4x4 conversion
 

You convinced me to box mine, so its only right if you box yours too right? :lol:

Re: Finally starting my Longhorn 4x4 conversion
 

You got me there. :lol:

Re: Finally starting my Longhorn 4x4 conversion
 

Ok, here's what I have to finish before I can work on the Longhorn a lot. I'm porting and polishing a 24v head for a 2002 Dodge. We had this head milled and o-ringed. The o-ring provides more force to help keep the head gasket's fire ring in place and not blow causing a blown head gasket. I'm still in the porting stage. These heads are very hard and can be really hard to port.

This is what the stock ports look like. Intake side is on the left of the picture.

Non ported on the RH, ported on the LH.

Exhaust side. I will gasket match each port and feather it in to the exhaust ports. The smaller ones are stock size. I will flip the head over and do the lower portion of the runners later.

These are ported.

Re: Finally starting my Longhorn 4x4 conversion
 

You guys seen these?


Going to make them for the 12v first and then on to the 24v.:devil:

Re: Finally starting my Longhorn 4x4 conversion
 

Yes I have. They are still trying to get the braking power side of it to work better. They sound cool, but I guess don't brake well yet.

Re: Finally starting my Longhorn 4x4 conversion
 

i think a retarder / magnetbrake would work better ,
http://i00.i.aliimg.com/photo/v0/206...rake_parts.jpg
i have seen motorbrake stuff but i think it works by smothering the intake air while cutting the injectors the vacuum makes the engine resist reving when running downhill in gear , prolly whont work with turbo's as they get hurt when you cut the air intoo them ... sucks the oil right trough the seals

Re: Finally starting my Longhorn 4x4 conversion
 

I bet a magnet brake isn't cheap either. :lol:

Re: Finally starting my Longhorn 4x4 conversion
 

More porting pics. Man, this is a lot of work and hard on a guy's back. :lol:

It's hard to capture some of the angles and such with the lighting. :lol:

Re: Finally starting my Longhorn 4x4 conversion
 

Oh yeah, a couple of days ago I put on the LH door handle. That's progress. Right? :lol:

My ORD zero rates came today and I plan on putting them in this weekend.

Re: Finally starting my Longhorn 4x4 conversion
 

definetely not , i was looking intoo using a set of those for a dynomometer-rerthingamajig and there way up there pricewize , they dont wear out though as here no parts touching it kindah works like a dynamo creating its own power to create the magnetic field
the cast iron disk usually isnt coated verry whell and there sitting behind the transmission in the open air so they look like a big ball of rust when you do find them at a truck wreckingyard

there was a show on discovery some time back that incolved a landspeed record attempt using some jetfighter turned intoo a car , they used a thick aluminium disk that turned with the wheels and another one that was stationairy next to it on the axle with permanent magnets in them
to brake they put the plates with the magnets closer to the rotating disk and the magnetic field caused the disk to resist rotating , it worked harder if the wheels where spining fast and redused in drag when the wheels started spinning slower , it allso didnt create heat

Re: Finally starting my Longhorn 4x4 conversion
 

Nice job on the head porting, you can really tell the difference on those exhaust ports!

Now show us your weapon of choice for all that!

Re: Finally starting my Longhorn 4x4 conversion
 

Ok, I am guessing that zero rates relocate your axle off the center pin with no degree change correct? I am not getting the 2-hole, 3-hole thing. I have never used them before. Educate me.

Re: Finally starting my Longhorn 4x4 conversion
 

They are called zero rate add-a-leaf. they can recenter the axle or not. they are called add a leaves because they become a part of the springpack when you bolt them on with the center pin but do nothing to change the springrate like a normal add-a-leaf. the 2 hole three hole is the choices for moving the axle forward or back
