Well, I suppose it's about time for me to start this thread. It's pretty much been a year in the making now, and substantial progress is finally being made.

The Preface:
I'm sick of sheet metal. I wanted something low, long, stout, and maneuverable. I was initially leaning towards a V6 and 9's, but I don't have the budget to support that kind of thing right now, so I went with what I know, a V8, 4 speed, and rockwells. Kert offered me a job for the summer, so I obviously took him up on it and am building it in the DIY4X shop.

Preliminary Specs:
Vortec 5.3
SM465
NWF Black Box
Ford NP205
Steering Rockwells Front and Rear
49" Iroks
Re-centered Hummer Rims
~125" Wheelbase
27"-30" Belly Height
~6' Tall to the top of the cage
51.75" wide at the sliders
71.75" wide at the shoulders

One thing I was mentally butting my head against when planning all of this is that I'm a tall guy with big feet. Therefore I need lots of leg room and a wide footwell with 3 pedals. This added up to pushing the driver back or the motor forward, and with already bad visibility from being so low, I wouldn't have been able to see a damn thing. So...I decided the motor needed to take a trip to the back.

Anyways, the few pictures I have thus far.

The model I made beforehand:

Got the sliders and mid-plate cross tube tacked in last week. Finished up the mid-plate and tossed the motor and transmission on it last week as well. The drivetrain could come down another inch or two if I bought an LS1 pan and cut a new plate. But, I don't see moving the drivetrain down 1.5" (the most realistic estimate) moving the COG down more than a half inch or so, which IMHO isn't worth it.

Transmission is a standard SM465, motor is a junkyard 5.3. I'm using flipped Hooker LS1 headers. The exhaust will run back (forward) and turn into a Spintech muffler. Intake manifold is an LS1 with the EGR blocked off that I spun 180 degrees to put the throttle body right next to my ear. :lol:

The 465 is a 32 spline output, which will go through the Black Box and turn into a 31 spline to go into the Ford 205. The transmission bell is a later model aluminum bell with the mount for a hydro clutch slave.

Currently, the a-pillars, b-pillars, and three spreader bars (rear roof bar, forward roof bar, and lower windshield bar) are tacked in place, as well as the rear fender "hoop" and a couple of braces. Tomorrow I hope to get a better idea of the seating location and bend up a second b-pillar. The seats will probably be ~1' forward of the mid-plate in the pictures. This will give me quite a bit of storage room as well as better visibility.

More pictures in a minute or two.
 
Cage for the passenger compartment:

Rear structure, axle is at full bump, tires clear at that height in all the right places. The end of progress for today. Got some new lines. Tomorrow I'll mirror this on the other side, bend the main rails for the rear, and start on the door bars. I'm not quite sure how to tackle the front of the rig yet. There needs to be room for batteries, a fuel cell, a small tunnel for a driveshaft, and a winch.

The winch is giving me a hard time, as I'd like to put it out in front of the axle, but I'd also like the hood to dive a significant amount for better visibility. With as low of a stance as I have planned and the rockwell chunk in the way (because of the rear engine, the pinion of the front chunk will be centered), it's going to be difficult to brace the tube work to take the stress of a winch that far out. I've been considering mounting the winch behind the axle and putting only the fairlead out front. This would greatly reduce the profile of the nose, as well as the stress it will see. The problem with doing so is that in order for the chunk to clear the winch cable, both the winch and fairlead would have to be offset at least 8". Any input?

thats got to be nice..

no waiting for fab parts:D


You have no clue how far from the truth that statement really is!!:haha:

Let's try this one, MIkey, how long you been hitting me up about the hummer centers?

:haha:Yeah right. I've been after Kert for hummer centers for the better part of 6 months. I finally gave up and talked to Tracy today and put in an order, just like everyone else. :haha:
 
I think offsetting the winch 8" to either side would be ok, I see how centering it on the axle would be very difficult.

Why don't you think the front of your chassis could take a winch?
 
Looks good so far

What bender are you using?
 
Chris - From where I will be sitting, I can see the top of the chunk on the front axle. One thing I won't sacrifice on this build is visibility. So, the "hood" will miss the pinion brake caliper by a hair in terms of vertical seperation. I'm not sure if I can get enough distance vertically between the tubes to be ok with it. Once I get the other rockwell cleaned up and the chunk spun, I'll know a lot more. I'm having a hard time giving up the idea of being able to see my entire front axle just by leaning forward while I'm on the trail. :haha:

Howdiy - Pro Tools 105HD, homebrew hydro conversion.

Stomis - 8 lug conversions are crazy expensive. The 8 bolts you see in the picture are the bolts that hold the drive flange to the hub. Look outside of that ring and you'll see the 6 lug studs. ;)

I know what you mean, after linking the rear of mine there is no sheetmetal over the rear and I can see everything. Being able to see when the diff or driveshaft are hung up is pretty sweet.

Which winch?
 
8274 :crazy:

I have an M8000 that I could use (it needs a new motor, so I might as well order another 9.5XP motor). I just hate the idea of putting the faster of the two in the rear of the rig, and space is going to be tight back there.
 
Extremely. I'm gonna start a pool on how long it takes me to put it on its lid by grabbing first instead of reverse. :haha:

Kind of a tough call. The M8000 will be much easier to fit up front but you'd be hard pressed to convince me to switch from an 8274.

I forgot about that.

I call the spot for backing into someone else, second trip :D
 
Not to worry. I'm going to see if Scott will make me a BIG decal with the shift pattern on it. :doah:

You'd think that the reverse spring might be enough to deter you from accidentally grabbing reverse.

Of course, you'd think I would remember to turn off my line lock too :doah:
