Update on the Hemi Coupe:
After we aborted the dyno testing session, I couldn't get the schedule to work out for all parties involved to test again before drag week. My aim had been to test the eight carb intake versus the dual quad intake. But that won't happen before drag week so I decided to just go ahead and swap on the dual quad and test it at the drag strip. Plus I bought a different clutch controller, it's called bank shift Billy. It controls the clutch release through the hydraulic line using an electronic control that you access via Bluetooth on your phone. So you can adjust the grab point and the release rate in extremely small, precise increments The valve needs to get spliced into the line between the clutch master cylinder and the clutch slave cylinder.

So I got the dual quad setup installed. The throttle linkage arm on the firewall is pretty much centered in the car so that it could work between The two rows of carburetors. So I started working on a Rube Goldberg type jack shaft setup to operate the throttle arms on the left side of the four barrels. But that wasn't working out so I came up with a simpler idea which seems to be working.
Next I had to figure out what to do for air filters/air scoops. I have some vintage ones that I really like but they're going to be difficult in time-consuming to get mounted on there, and I couldn't figure out how to get filters into them. So I bought a pair of new ones from speedway. I got them mounted on there so they will work for drag week, but they're not my favorite as far as looks go.

Then when I went to install the bang shift Billy clutch controller I discovered that the fittings I bought to splice it into the line where the wrong ones. So I didn't get that installed yet. I also installed a diaper on it and had to make up custom bracket to prevent it from interfering with the steering shaft, but that wasn't too big of a deal. The diaper covers up the sight glass that I have on the side of the oil pan so it's not a simple glance to check the oil level anymore. But it's not too hard to unstrap one corner and drop it down enough to see the site glass. At least if the motor is not piping hot.

I changed the oil and filter, and the lube in the transmission and rear end, fixed the handbrake, did a bunch of miscellaneous little repairs and cleaned it up. I was hoping to get up to brainerd for a test night last Wednesday, but I wasn't ready. So yesterday we went to Rock falls. I was suited up, strapped in, three cars from the burnout box when it started raining. At first just a little bit. But then it poured. Eventually they called the race and I didn't get to make a pass.
So this morning we went to Grove Creek which is the first half of a drag strip, and I made one pass.

The trunk munky is too busy to help so I recruited my son Cam to come along. He's pretty smart with technical stuff so he was able to get the GoPro all set up and adjusted the frames per second that it was filming in so that now it will actually record the readings of the air fuel ratio gauges. Previously the GoPro would not record them they just showed up as a flashing light. We also mounted a GoPro under the car to get a good view of what the suspension does on launch.

I used my best guess to set the clutch tamer which is the old clutch release mechanism. I launched it with the pedal on the floor and the two-step set at 5,000 RPM. The rear tires hopped a bit upon launch and the shift light came on almost instantly. I grabbed second, but the shift light stayed on, so I went for third, finally the shift light went off. I was thinking I had tire spin, but in hindsight I think it was clutch slippage and I had to grab point on the clutch tamer set too low.
I did manage to get it into fourth gear before the end of the track, and went 6.51 at 111.

But some liquid sprayed on the windshield. I wasn't too worried about it because that's happened before when a little bit of water leaks out of the overflow tank or something. But when I got back to the pits, Cameron noticed right away that the radiator overflow can had a mixture of oil and water oozing out of it through the weep hole on the top.

After it cooled off a little bit, I pulled down the corner of the diaper to look at the sight glass on the oil pan and there was no oil showing. So we pushed it into the trailer and came home. I have it in the shop, getting started on trying to figure out what's wrong.
Hopefully it's nothing that I can't get fixed promptly. I'm definitely not throwing in the towel at this point.

Now I'm taking a quick lunch break, And hopefully I'll have it pinned down sometime this afternoon.
