I decided to upgrade the steering wheel to something that allowed even better gauge visibility. This is a 350mm Momo Mod 78. The "straight across the top then drop", three spoke set up is a big improvement over the previous wheel - without moving my head at all, there's virtually no part of any of the gauges I can't see. The Momo hub is on the way so pardon my manual positioning in that last pic...

And in keeping with the "RaceRod" theme, I decided to eliminate the stock, column-based turn signal and wiper switches in favor of "remote" steering wheel buttons.
The Infinity Box electrics allow for programming such that I can have momentary switches that trigger the signals and the brain will cancel them after X seconds or not at all, if the brake lights are on.
Same deal with headlights: I can have a high beam switch on the wheel that can either flash-to-pass the brights or turn them on/off.

Beyond signals and hi beam, I'm not sure if I'll have other functions accessible from the wheel, so I made a couple button plates. It's simple enough to add or remove space for more or less buttons.

Gauge cluster and wheel works together like a factory set up!

88 more pages until the first test drive!

Major milestone completed today. The engine ran again for the first time since I got it from Tony @Cracker .

Presenting the dyno results for one LS3 with ITBs.

518 hp
463 lb/ft

I think that ought to about do it.

I absolutely can not wait to see that engine in your car. Of course hearing it would be the icing on the cake. (IMG:style_emoticons/default/beerchug.gif)

Yep, I'm really happy with the dyno results! Seeing it run certainly jacks up the motivation to get it on the road.

But I couldn't help myself on another redo:
Over time, I started to notice (and dislike) the way the shape of upper/outer fire wall panels just died when they ran into the dog house. (in the 2nd pic)

So I sliced the cap off the dog house and started on a piece that carries that line all the way across the fire wall.

Form over function triumphs again...

And I need to select the needed switches so I ordered a few different kinds to determine what I like. Initial plan is looking like this pic: stealth black for the turn signals with something different for the high beam.
The final switches will likely be sourced from the same manufacturer but I do think I'll mix up the look.

switch faces plastic or aluminum. Either way it could be cnc milled or laser etched. If AL, I would Cerakote them then laser etch the symbols into them for what they are. You can do some very neat stuff with CeraKote and lasers.

@914forme Stephen - The switches are AL but I think I'm going to leave them "blank", at least for now.

And the Momo hub came in so here's the wheel all set to go. It's working out just as I'd hoped.

As always, recent mods looking great Chris!
With all that horse power and as light as this car will be, you might have to load the trunk with lead weights to hook it up.

Time to get all the fire wall panels prep'd for install.
I want all the rivets to align vertically. The fun part is that the rivet line on the main panels is level but the line in the upper panel is slightly curved.
This means I can't just set the rivet fan to the same distance since the rivet line on the curve is longer.
So, I used the laser level, positioned it appropriately for each rivet and marked directly, vertically above each main panel rivet.
It's always a bit more complicated than you think it'll be...

I reshaped the corner radius on the new dog house upper panel then marked and drilled the doghouse for rivets.

My wife was quite funny when she saw all this in process. Her comment:

"Well, you sure know the drill..." (IMG:style_emoticons/default/lol-2.gif)

@Andyrew , I hope you got that Cleco stock!

@Morph914 Thanks John! I know, right? It should be "interesting" with this set up.
And how's your build coming along?

I think you should leave them in there permanently!

It’s going well, my goal was to get the tub into epoxy before the humidity hit, and I was able to do that. So what little body work there is to do will be completed in the fall when cooler and drier weather come back.
To keep the momentum, I am going through all the parts cleaning, painting, replacing bushings, bearings, etc., Hoping to paint this winter. I do feel a little guilty already having the car to this point after following some of the builds, like Brent’s. Thanks to you for selling me a dry car! (IMG:style_emoticons/default/aktion035.gif)

I have a lot of little things to finish. Necessary but not too exciting.
Today, it was fabbing the little extension panels for the driver side lower fire wall so that panel extends all the way to the long, above and below the seat belt retractor recess.

I also took the opportunity to braze in the e-brake guide tubes. It's all coming along.
