Building a Rock Crawler!! FABN801

Added: 2026-05-09

[00:00:00]All right, welcome back to the channel and we got a new build going on.

[00:00:08]You guys remember the giveaway that we had a little while back. Anyways, the guy that won it wanted us to build it build it out a little bit. So, this is what we got.

[00:00:20]3800 supercharged. I can't remember the transmission. I think it's out of a Jeep.

[00:00:25]Uh Behemoth Dana 300 14 bolt in the rear, kingpin 60 in the front. Anyways, we're going to get this all uh get the motor mounted, get it all linked up, shocks done for him, and uh anyways, see what else he wants to go from there. But, what I'm working on right now is some motor mount plates.

[00:00:50]So, what we're what we're using are these three three bolts on that side.

[00:00:56]And then on the passenger side we're using these three bolts as well.

[00:01:05]So, um I uh got ahead, didn't realize it, but I got them drawn up on the computer.

[00:01:20]And that's that's what I came up with right there.

[00:01:25]Um Took me a couple tries on this driver side one, just getting the hole location right. But, got it cut out. Got them cleaned up. That's what what I designed.

[00:01:39]So, I'm going to try and find some hardware and get these mounted up.

[00:01:46]All right, guys. So, I'm working on the motor mounts and uh I got these tabs Yeah, these shorter tabs go go on the driver side. Or no, excuse me, passenger side. And these tabs are just I think 3/8 longer just so they can clear the head of that bolt right there. But they're going to sit in just like that.

[00:02:08]And then we get these bushing kits and a little gap and so we're trying if we ran this style, they would anyways, it would be nearly or it would be impossible to get bolt in and out of those two.

[00:02:26]>> [snorts] >> Um so what we did, I just shaved up that inner tube, that metal tube, sleeve, whatever you want to call it. Just trimmed it up that half inch, whatever it is. So we got that.

[00:02:40]Um so now I'll get this all jigged up with a bolt through it and uh get it tacked up and get it on the car.

[00:02:54]So Matt's just getting a My mess up fix.

[00:02:58]A mess up fix. He had a hole that was a little small so he's just drilling it out. But man, you guys, this car is going to be something else.

[00:03:07]3800 supercharged and as you can see it's super narrow and not very tall either. So this is actually a motor I've really been leaning on for my next car.

[00:03:19]It's mated with a automatic transmission right to the Behemoth Dana 300 and I tell you what, that case is beautiful, you guys.

[00:03:26]There's a couple other companies out there that's tried to make them. They've been unsuccessful with keeping the company alive and I think this one is going to be around for a while.

[00:03:37]So he's going to be running a 14 bolt non-rear steer and of course this is our new hatch lizard chassis.

[00:03:48]So Matt's going hard right now trying to get this uh transmission mounted and the motor plates on the motor. As soon as he gets those on there, we'll be able to take some measurements and cut out some tubes to get the motor mounted to the chassis.

[00:04:03]In the meantime, I'm cutting the chassis. So, I will be back and forth with the camera watching this young buck handle that budget build crawler.

[00:04:16]All righty, guys. So, I got the motor mounts on. Here, I'll show you guys.

[00:04:22]So, I got the motor mounts on. Tabs are all welded on.

[00:04:26]I made a whoopsie on this one and welded the tabs on the wrong side, so I had to drill a hole. That's what you guys seen when Thomas was showing you. But, we got I had a buddy of mine from my last job make these little mock-up bushing kits.

[00:04:41]So, well, the aluminum, I should say. So, um I'm going to get these and uh get those bolted up so we can pull some measurements and get a tab. I think what we're going to do, we're going to take a piece of tube from there and then get the motor Yeah, get the motor where we love it.

[00:05:07]Get that tube the tube on on both sides and then we'll uh I need to come up with something for the mount. We got the crossmember in, but I need to design something for to mount to the crossmember.

[00:05:23]Anyways, once we get that done, we'll be able to um Yeah, get pull these little janky stand engine stands off, get it all blocked up on some wood, and uh make some measurements. And we're going to make a skid plate come from right here all the way probably to about right here, just under the Yeah, just under the front of the motor.

[00:05:52]And then back. And then we're going to tie it down. Just like we did on the Sin City chassis, if you guys remember on that one.

[00:06:01]Um we had it mounted up top and then down from the bottom of it as well, just to uh kind of tie everything in.

[00:06:08]But Yeah, so I'm going to get going on that.

[00:06:12]And uh yeah.

[00:06:37]All right, you guys. So, we normally build all this setup on our fab table.

[00:06:45]But we're in the process of making a new one and for some reason we're going to do it on the ground. So um what we wanted was the motor to sit a little bit drop more driver um on this car just so we can make sure we have the drive shaft clearance um on the passenger side for because it's a kingpin Chevy kingpin 60.

[00:07:12]Um anyway, so what I did I just we marked center and then down at the end of my ruler here square, I just measured up to the center of the bell housing bolt or not bell housing.

[00:07:25]Oh my gosh.

[00:07:27]The balancer bolt and the crank bolt right there. And then same with on the back side.

[00:07:33]I uh just took my square up to there, measured it up to the center of the yoke and we're about 5/8 front and back offset inner.

[00:07:45]So, that's where we want it.

[00:07:48]Now, the hardest thing is to not bump the chassis while it's on the ground cuz it it moves really easily. Normally, we'll put little staples kind of thing, staple clamps over the tube on each side um and weld it down, but because it's concrete, we don't have that luxury on this build. So, yeah, you just got to be very cautious, but now I can get my measurements and get that drawn up um for the tube the motor mount tubes coming down to catch catch that.

[00:08:39]All right, so I got I just barely measured and the driver is going to be 6 and 1/4 on center. That's center tube center tube.

[00:08:49]And then passenger 8 and 1/2.

[00:08:53]So, um I'm not sure if we're going to put this in the computer or if we're just going to cut it and uh do it by hand. It'd be easier if we did it on the computer, but Thomas is currently cutting out a junior lizard for a customer. So, um yeah, we're going to figure that out and go from there.

[00:09:22]All right, you guys. So, >> [sighs] >> I got we got this piece drawn in, um but I guess my measurements when I put them in the computer were a little off cuz it was long. So, I uh just had to go the uh old-fashioned way, I guess, whatever you want to call it, and uh grind it, notch it by hand, basically. I just shortened it up, but I got it to fit really nice in there.

[00:09:50]And it's a good rough rough start, at least, so doing it on the drawing.

[00:09:57]If it's not perfect, it's at least close.

[00:10:00]Um so, now uh I get to do the same exact thing on the other side.

[00:10:05]And uh yeah.

[00:10:10]Stay tuned, I guess. All right, you guys. So, I got measurements in the computer, and I got it cut out.

[00:10:19]Uh I messed up on my original measurement to cut this one, but it was a little too short. I didn't add the inch when I measured my distance from bushing over.

[00:10:33]But, that's okay. I uh cut a new piece out, and it fits in there pretty good.

[00:10:38]Not perfect, but pretty good.

[00:10:41]Um it's all fillable, and nobody will ever know.

[00:10:45]Besides you guys.

[00:10:46]Uh anyways, now uh I got the engine itself packed up.

[00:10:52]We're going to or I'm going to throw a ratchet strap over the yoke of the of the T-case. We're going to run it up and around that roof bar, back to itself, just to get a little bit of pressure off, or just to Yeah.

[00:11:13]Float it a little bit, and uh I need I mainly need to have get enough space so I can uh figure out what the bolt pattern is on the bottom of this transmission. Um Yeah, so once I figure out the distance there, then I can come up with something to mount to make an actual legit mount to that crossmember. And as you guys can tell, we whoa the crossmember is a little angled. So, the that is because the T-case sits so well on this side and it everything is just so far forward that if we move this forward more, it would be Um yeah, here you go. If we move this more forward, it would be directly in line of the bolt cuz the bolts are centered of that flange right there.

[00:12:15]Uh yeah, so that's why we had we had to scoot it back and it's a little weird.

[00:12:22]It looks goofy, but it's going to work just fine. I'm going to make a little tab that makes it sit up and fill it in and another one of those things, it'll work just fine.

[00:12:36]So, um uh let's get this all jigged up so I can get some measurements.

[00:13:14]All righty, so I know Thomas has shown you guys a whole bunch of times, but I'm going to let you guys watch.

[00:13:36]>> I live inside my own [music] world of make-believe.

[00:13:42]Kids screaming in the cradles profanities.

[00:13:48]I see [music] the earth through eyes covered in ink and bleach.

[00:13:54]Cuz all the ones who heard my cries and watched me weep.

[00:14:00]I love everything.

[00:14:03]Fire spreading all around my room. My world's so bright, it's hard to breathe, but that's all right.

[00:14:12]>> [music] [music] [music] [music] [music] >> Tape my eyes open to force reality.

[00:14:39][music] Why can't you just let me eat my weight in glee?

[00:14:48]I live inside my own world of make-believe.

[00:14:54]Kids screaming in the cradles profanities.

[00:15:00]All righty, so now I got this skid uh sitting there.

[00:15:06]And I even scooted it over just a little bit cuz the motor's a little bit more driver.

[00:15:13]But I still wanted to make sure that there's enough room for the drain plug to come out, which there should be.

[00:15:21]Um Anyways, so now I'm going to work on some motor mounts to tie into the skid to just make sure it stays solid and just extra protection.

[00:15:35]Extra whatever. Anyways, so on this side we're going to I think I'm going to do something like what I did on this trail monitor.

[00:15:46]Anyways, have a little bend to avoid the oil pan and then just straight down on this passenger side. So and I can come straight down and then just find a piece of tube with a little bit of bend bending it to do that one and uh yeah, should be golden.

[00:16:09]All right, [snorts] so Thomas kind of pointed something out to me on this skid um that kind of looks goofy having just that 2 in or whatever of a overhang right here. So what we're going to do, we're going to cut this off, trim up that end just a little bit and suck this so this point will be right here. So this will all tie in and look like it's one piece to a point.

[00:16:39]So I'm going to go ahead, get these two tacks cut. I'm going to leave this up in place.

[00:16:45]Get these two tacks cut and see if I can break these tacks.

[00:16:50]Um it's going to be a pain in the butt, but I think we can do it and it'll be worth it.

[00:17:47]>> Okay guys, so as you guys seen [snorts] we got the motor all lifted up and suspended in the air and all that fun stuff. So now I can go in and just I'm going to hit it every all the welds with a wire wheel and uh the welder's being used right now, so I'm going to do that first and then once I get that done, hopefully the welder's available and I'll get the backside of these.

[00:18:11]Um just cuz obviously motor was in the way, so couldn't get to it.

[00:18:16]Um so yeah.

[00:18:22]>> [snorts] >> All right you guys, so we got the motor and fully welded or fully mounted and uh skid plate made.

[00:19:06]So next up [snorts] on the list is going to be getting axles mounted and shocks and get the suspension fully done up.
