Fuel cell safety loop and mount.

Along with the fuel pump mount.

Space up front was pretty tight so I had to get a little creative to fit the fuel system.

Had a customer show me this style pre-filter which helped save a bunch of room and plumbing. It's a bulkhead filter that goes inside the fuel cell.

Post filter support/mount.

After a very long wait, the new throttle body finally came in from Wilson so I could cut the hole in the firewall for the throttle rod.

This thing is like a piece of art.

The old intake isn't gonna allow the throttle body to clear my 4" cowl hood, so I'm changing from the sv565 intake to its predecessor, the 2927 which will need a fair amount of machine work to fit due to the 2 axis cylinder head dowel shift on my engine. Will also be ported to try and match the performance of the old intake.

Here's a picture a buddy sent comparing the old vs new height.

Mocking up the new intake with the restrictor plate I run.

Trans overflow canister fabricated & mounted.

Radiator support rod, coolant overflow and vacuum pump puke can mounted.

Built the car with a mockup th400 case so I did a quick mockup with my actual trans, my Coan 400xlt that RPM has serviced in the past.

Had to get a racing buddy to come over and repair the worst of the body damage. We also removed the gas fill door since the tub ran through the middle of it.

Passenger side was a bit beat up too, now all fixed up.

At this point the car was mostly complete so I wanted to weigh the car to see where the weight might be and to see if the weight bias worked out as planned.

The class I run doesn't get radial prep, but I've raced on a radial for nearly 27 years. So I put myself at a bit of a disadvantage being on the radial. Knowing this I can't run the front end as nose heavy as a heads up car on fly paper prep, so I was shooting to be about 54% on the nose which I knew was gonna be a challenge with an iron block BBC under the hood. For this reason I moved the main hoop back which moved my driving position back, and used all carbon fiber body parts in the front. Will also have a carbon roof skin.

I am keeping the stock rear hatch and glass as well as keeping stock steel doors with factory glass and power windows.

I then stacked everything in the car to simulate race weight.

And this is the result, with and without driver. Ignor the corner weights being jacked up as my floor isn't perfectly flat and I use scale leveling pads when scaling the car to setup the suspension.

It wound up a little heavier than expected, but given the stock doors and hatch, plus I built the back half heavier with 1 1/2 x .065 for weight in the rear, it's not a huge surprise its a little heavy. But for my class, we have a 2800 lb minimum weight, so I'm still gonna have to add 150-200 lbs ballast to be race ready.

Can't forget the chute mount...

Again, due to space constraints I had to get a little creative here too. I dislike the 3/8" or 1/2" tube mounts for spring launcher chutes. I used a mono-stalk mount on the Malibu but had to change the mounting configuration for the Mustang.

Chute cable strain relief.

That pretty much was it for the fabrication on the car itself, but one last fabrication project was to build a transport dolly so the car could be sent for powder coating, then body/paint work.

And strip the car down bare...

Todd thanks so much for posting the progress of your new ride.
I can't say enough how impressed Iam with your work.

Thanks for the kind words Jimmy.

Glad to see some are enjoying following the build. I believe it's something not many get to see in detail to get a feel for how much time and work it takes to build a car from scratch.
