General Tech Rockwell Buggy, take 2.

That's huge. So cool to see that you have that much help.
We weighed the chassis the other night. 870lbs bare chassis with out the bottom skid bolted on so close to 950lbs total. Each axle was 807lbs with out tires so right around 1200lbs per axle. It will be a 5k girl. We have friend that just got some race scales to weigh things so we will have to have a weighing party.

So little update before I head back to work for two weeks.

As Cory posted I got it all painted up etc and back to a rolling chassis. We got all the correct hardware in for the links and tightened them down. Then we got the motor stabbed in and we began the fun task of reassemble parts and wiring. I have been tackling the wiring and reassemble parts and Cory has been doing some needed Fab on it like putting bigger fans of the radiator, maching a block for my transmission temp sensors, and helping me wrestle crap into place.

So one needed Fab thing I did was mount the rear bumpstops, pads, and rear limiting straps so I made them into a single platform

Then after that got all the junk back in the trunk. Cory had to get creative with a hammer with the way the fuel tank sat I its mount. Also go the fuel shut off and filter etc mounted in

And while he was doing that I was getting blisters on my fingers from all the damn wiring. Got most of the sensors etc for the motor ran down the passenger side due to I'll be running all the front hydro stuff on the driver side. over all I'm pretty happy with my rats nest of wiring. Under the dash could be cleaner but eh. First build.

And here's the trans/atlas wrestled in by Cory mostly.

After this I did some more wiring to the abck of the chassis like the fans wires, rear steer, winch conrtols, lights, fuel pump, etc. Also got the brake lines done with an allstar line lock aka park brake worked into it also pictured is the neat transmission sensor block Cory tiggered up.

Then I got the winters shifter in and adjusted up with my Harley peg shifter

And also got the exhaust all wrapped up and in. Front tubes are orange and the rear is silver ish. Was all supposed to be orange but I've lost a roll.

Then I'm needing some guidance here. We got it running. All fluids etc checked and fired up. It's having an issue of running rich and idol is surging a little and staying right around 1200-1500 with small back fires every now and then. Tested all sensors, adjusted the tps to it's specified range, fuel pressure is perfect, no vacuum leaks or intake leak. Haven't checked timing yet, and haven't checked the ecms temp switch it have noticed it seems to spray a little more fuel down the driver side than the passenger. Replaced the injector, made sure all the passages were clean and clear and still does it. Any thoughts? Oh and I wired in a 3 wire o2 sensor and it's reading good too

And here's a bunch of miscellaneous stuff.

My beautiful Hughes torque converter to compliment their valve body I put in. Stall range is 2200-2400

Then this cute little back up light switch we rigged up.

Then my rock lights. Pretty decent little guys, will have about 14 all around the bottom.

WOW, that's a ton of work. If you're not careful you'll be in a running buggy before too long. Nice job. To me that missing sounds like an O2 sensor, but I'm guessing you had those deleted from your ECM.

The O2 is a brand new ac Delco 3wire that is supposed to be in the 14.7 range like the factory single wire. All the sensors minus the spark control module are new bwd or ac Delco. I'm thinking it's one of three things, bad ecm coolant sensor, bad timing, or bad ground

About to be on my way home and here's the plans for this home time:

Figure out motor issue, pretty sure it's timing but we'll see.
Get all links adjusted and square up the suspension.
Get the hydro lines built
Finish up wiring
Check all fluids
Get drivelines in
Finish up brakes
Finish putting interior in

And on another spectrum of updates, hot parts ordered like coil springs, SFI approved and dated harnesses, and rear winch rope. Crappy part is that the coil springs are coming all split up. PAC Springs only had 4 out of the 8 I need in stock and the rest are on back order till Lord knows when.

Anyways stay tuned.

Spent some time on the motor today, reset the timing to TDC and 0 advance. Ran it up to 4 degrees, cranked down the distributor, plugged in the bypass and she ran a little better, stayed around 1200-1000rpms. While it ran I re did the spray around the manifold test and found a tiny leak on the driver side of the TBI to manifold adapter plate. Pulled it apart, made a new gasket, still idoling high.

After this I took to the internet and started checking sensors. Everything was checking out fine on the harness end and then it started idoling up and down from 1500 to nearly dieing. During this I kept hearing a clicking noise from the TBI and saw the IAC pushing in and out quickly. I pulled it out, got a new one, and Bam! Runs just fine now!!

Also got in my 4 coils from PAC that they had in stock. Now the waiting game for the next 4!
