    When I have some time, I'll provide an update on my weekend at Moparty. For now, a couple highlights. The only tool that touched the car all weekend was a torque wrench to check lug nuts. I got 17 autocross runs, 3 drag passes that were hot laps, and 18 3S runs. I'd say I put this thing through...

    Hemi Swapping a perfectly good 70 Duster

    It’s from Tanks Inc. I don’t recall the brand. I’ve planned on upgrading the fuel system at some point anyway, so not a big deal.

    Hemi Swapping a perfectly good 70 Duster

    For those following along here, I went to autocross this past weekend. This was the first time since I had the power steering problems last time out. I'm happy to report the modifications (corrections) I made worked. It was also the first time successfully around the cones with the hemi. Very...

    Here's the course map. I'd say the second big turn on the top right, it was very neutral, but no 4 wheel drift because speed wasn't high enough. The long sweeper around station 2 I could have definitely done some drifting there, but still very controllable. The last big sweeper had some speed...

    I have until midnight Wednesday to cancel hotel rooms. Worse case, I wait to load up Thursday morning and just get there late.

    It rained Saturday afternoon and Sunday last year. Right now it's 50% chance of rain, which is also 50% chance it won't rain. Too many unknowns right now. Also, the current path is literally the road I take up there. It's no fun driving in torrential rain with strong wind gusts towing a trailer...

    I attended my local autocross yesterday. It seems my power steering problems are fixed. This was also my first time with a successful run around the cones with the hemi. My first run was a disaster, likely due to cold tires and me being unfamiliar with the throttle input this thing needs. I...

    Is 1/2" leaf spring relocation worth the trouble?

    I trimmed the lip on my quarters. I think it's only about 1/2" wide now.

    Hemi Swapping a perfectly good 70 Duster

    Oh, pre heat. Sensor connected directly to the gauge "A" always heats up faster. Not by much, maybe a few seconds.

    Hemi Swapping a perfectly good 70 Duster

    I installed the new 1" bungs right on the surface of the pipe to get them further out of the exhaust flow, instead of recessing the bung. Innovate says they don't need to be in the flow, so why not keep them protected by being further away. The tip of the sensor is even with the 1" bung, so I...

    That's the highest the sensor reads. The engine isn't running in this photo.

    Hemi Swapping a perfectly good 70 Duster

    I updated my build thread with this information, but I figured I'd put it here as well. Earlier in this thread I mentioned I failed an O2 sensor. Well, the second one didn't last long either. As it turns out, the bungs I used were only 1/2" tall which put the tip of the sensor into the exhaust...

    I've really been thinking about trying the Ride Tech spindles for the GM A,B,&X body that accept the corvette hub and brake assembly. Since I already own the hubs and brakes, I would only need the spindles and steering arms. If I were to go with the Ford version, I'd have to get brakes, hubs...

    How to make your G3 alternator a 1 wire connection

    I wanted to provide an update on this alternator modification since I now have about 600ish miles on my G3 swap. The voltage regulatory is working perfectly. Just last week I drove to a cruise night 70 miles from home. This was the longest drive at night since getting the car back on the road...

    I think I may have forgotten to mention I changed fuel injectors recently. When I started to have wideband problems, I was questioning if I had an injector problem causing the lean spikes. The injectors in the hemi were the same ones I had in the LA, which were SRT4 injectors. I took them out...

    Well, I do have some maintenance to do on my truck before I tow for 1200 miles. As for the car, the biggest thing to do is make an alignment adjustment/check. After that, its just pretty much nut and bolt check, and change the oil in the engine since I'm sure its broken in by now. We have a...

    I'm getting anxious! For once I don't feel rushed trying to get the car ready. But still lots of things to check.

    I know I've been a little quiet lately. Lots of other things going on besides car stuff. Some may remember I killed an O2 sensor shortly after getting the hemi running. I replaced it and it worked fine for a very short time and that sensor failed. I didn't quite understand why since I had...

    6.1 Hemi Internals.

    I'll throw something out there for everyone to ponder. I'm sure not everyone has been up close and personal with a locomotive engine, so I'll explain. In particular, GE loco engines use huge head studs as you can imagine. They have a tool that stretches the stud and you simply run the nut down...

    Is 1/2" leaf spring relocation worth the trouble?

    That will likely require lots of fender modifications. That wheel has 5.5” of “front space”, which is approximately 2” more than what fits in the fenders without cutting anything. It will definitely hit the front edge of the fender and depending on how much caster you run, it will contact the...

    Is 1/2" leaf spring relocation worth the trouble?

    Man you need to get these things mounted up. I’m anxious to see how they look. I saw they were running a sale on some sizes of the bronze finish for under $200/ea. if they would have had the sizes I wanted, I would have bought them and had them re-powder coated. Only the 18x9s were on sale.

    Is 1/2" leaf spring relocation worth the trouble?

    They are the attack series. The color I have isn’t made anymore. After talking with a Holley guy at Moparty,(Holley owns rocket now) he happened to be the engineer that worked on the wheels. Apparently they had color match problems between batches with the color I had. So they discontinued it.

    I can measure it for you. It’s not on the car anymore, so it’s easy to measure. Actually thinking of selling the spindles with hubs and calipers. If I remember correctly, the rotors are just under 14”.

    Is 1/2" leaf spring relocation worth the trouble?

    A-body 8-3/4. They are rocket racing wheels. Finding a wheel and tire combo is tough. I’ve found the rear size is much easier to find than the front. If you want a 9” wheel on the front, you will need 6.5” of backspace. They are out there, but then you won’t get the same wheel with the correct...

    For those following along that have any interest in pro-touring cars that actually get driven on the autocross or race track, I started a podcast talking to guys that own and drive these types of cars. They aren't all mopars. The first two interviews are Fords, the second two are Mopars. That's...

    Is 1/2" leaf spring relocation worth the trouble?

    I run and 18X10 and a 275 tire with the offset front hanger and slider. I autocross regularly and I have zero tire contact. However, I did before changing to the slider. The tire would rube the inside the fender well. I do think I could fit a 10.5 wide wheel and run a 285 without contact...

    '70 Dart 392 Project; what direction?

    Glad you are making some progress. There's always that "Ah-Ha" moment when things start to work. You know, the thought of adjusting stoich for modern fuel with ethanol in it never crossed my mind. The problem is you'll never know what ethanol content you have unless you use a flex fuel sensor...

    Hemi Swapping a perfectly good 70 Duster

    I added a cooler to the return line. It’s a plate and tube style with 10 plates. It’s approximately 12” wide. I did a quick 10 mile ride after I got done, which would had previously made the fluid 200+ degrees. I shot it with the infrared immediately when I got back and it was down to 170. Last...
