The government wouldn’t allow this new. Stiffer crash/ roll over guidelines now , I bet anyways. That’s why the concept Challanger changed so much with production cars. I bet usage of existing under pinnings might of helped the change in production cars too. I’m a Chevy guy, but the concept Challanger looked great. Made me consider buying a new car.

Just two Gates 1/2 hoses with a molded in 90 degree bends. Ask your parts store for them.

Do you use the ecm to control the cooling fans? Curious to what everyone does to control the fans with AC request?
Thanks and beautiful build.

Yes I use the ECM to PWM the fans. This is not how the GM crate cal is set up. I have to make a new cal to do that.

The fan runs off 3 inputs - Coolant Temp, AC head pressure and inlet air temp post intercooler bricks.

Ok.Thanks I've intalled a few gm crate engines with gmpp computers and used the fan wire from the gmpp harness but there isn't a way to tell it when AC is turned on unfortunately.

You can use a trinary switch on the a/c line, so the computer controls the fans whenever the a/c is off, and once the a/c is on the switch bypasses the computer control and turns the fans on automatically. I'm going to be using a standalone PWM controller for my twin Ron Davis fans.

Correct me if I'm wrong, but the GM ECM doesn't use a trinary switch when controlling fans by way of PWM.

Doesn't get much cleaner than this, the wheel fitment is also perfect! Can't wait to see how it does on the street & track.

Mark have ever had issues with the latch in the hood popping open at high speeds? I'm not sure if your using the original latch mechanism. I've noticed many car builders use hood pins and my father before me has warn me about the risk at high speeds. thanks sir.

I don’t like the look or function of hood pins. I have run a stock hood latch on most of my cars.

We ran a test at work to see the force on a hood latch on a 2008 CTSv at 190 mph. It was over 300 lbs of force trying to pull the latch open.

I have not had an issue with the stock latch with my Carbon Fiber hood. But we have a big steel reinforcement plate in the hood that the latch bolts into.

If you want to be 100% sure do some old school hood pins. I personally hate them.

I can say at 170 mph in my cars you can see the corners of the hood being forced up by the under hood pressure. Another reason I have hood vents.

Good luck!

Dash
 

Mark,

I like the finish on your dash - is that just an off the shelf crackle paint or something else?

This build is beautiful. So right in a subtle way, and not overdone. As someone who is trying to emulate much of what you've done in recent builds, one of the hardest things is to keep things simple and logical in both function and appearance.

It is our local powder coater wrinkle black powder coat. I like it. It does not scratch and gives a nice look.

Thanks, for the complement. I like simple complex things. This car has a lot going on but it looks fairly simple.

Matt and the gang at Sled Alley do a fantastic job with all the little details.

Mark

This is an incredible build! I can't even begin to imagine the amount of engineering and thought that went into this, but it looks just absolutely beautiful!!

Amazing build. Thanks for sharing the process

Evening Mark,

I really love the look of the black finish on the radiator and AC condenser. Do you have any tips or suggestions to get the OE look that actually stays on.

Thanks in advance.

Not to be flippant but hire a good painter. I honestly have never painted a radiator until I did Red Devil and the Dutchboys suggested painting it.

I know this time around they painted them black then applied a satin clear to get the correct sheen.

On my Blazer I used a lot of SEM Trim Black. At home when I need to repair something Trim Black works great.

Good luck

Mark

LOL....SEM Trim Black makes me think I'm a painter.

You guys buying that high dollar name brand spray paint. I'm over here with ACE satin black going to town on my radiator, lol.

Another great build, Mark. Your team did a great job.

I go back and forth between SEM and VHT rollbar & chassis paint. For me, VHT lays down nicer.

I feel they spray the same but the VHT is easier to find for me.

I had the Recaro reworked with red houndstooth material and the back seat done to match.

The Dakota Digital dash and AC controls are linked together and have matching lighting.

Getting closer

I like the red houndstooth, very different,

Holey cow, that all looks fantastic.

Looking good...
 

Mark,

Wow, just when one wonders what else could be done the all time classic.
You and your team come through, knocking it out of the park...

Understated elegance, precision, execution.
Congratulation's on completing another one and sharing it with us.

Thanks, Dennis

Well this is why repo parts suck. Stock glass was all scratched up so we need new glass. Easy right?

We went through 4 sets of glass to get door glass that fit.

First set the glass was wavey

Second set the door glass curvature was way off. Could not be made to deal

Third set same bad curvature

Forth set fit and was not wavey

WOW! That's huge!!!
I'm skeptical about using Fesler flush mount glass on my 69. I've read good things and bad, about the quality. Luckily he is only a few hours from me, but still, I have to wonder about QC.

Where were you getting your glass from?

As always the attention to detail and execution is amazing!

theres a member here i know who you couldnt pay to use Fesler again . i think with some work stock glass can be flush mounted at a huge savings $$$$

And if your luck is like mine and you get a big ‘ol rock chip in the first 50 miles of driving (I-17 north, verde valley) you’ll only be kinda miffed, not totally pissed!

I went home yesterday and there was a nice article in Road and Track
about Mark and his cars. Good to see the protouring guys are
getting National attention... Mark has always been a standup guy
Came by and talked to me when I had my car at Sema for the
Optima Challenge...

Congratulations Mark and thank you again for helping all
of us with your knowledge
