8.50 index build
 
Hello all, long time member, just never had a class car.

One year ago I had a bad top end wreck with my 8.50 index Malibu that I built, owned and raced for 27+ years. Car made a hard left past the finish line, put me into the wall which then caused the car to barrel roll as many as 7 times I'm told. I don't remember any of the accident, so no apparent cause was found.

A couple weeks after the crash I was able to source a body to begin building again. My dream car was gone so the new car would simply be a purpose built race car, chosen for ease of parts availability, low purchase cost and light weight.

I have many, many pics of the build in detail, not sure how much interest there would be to see this project.

The first car looked very nice, i'm sure this one will be too. I am always interested in any build!
Keep up the good work and keep posting please!

Found alot more rust than I was hoping for. One area I really didn't want to get into was the front frame rails which have a reputation for rusting out under the master cylinder and combination valve.

https://i.imgur.com/CJLd2kl.jpg

I tried ordering a replacement frame rail kit but didn't like how it was going to install, plus I found an issue with the factory placement of the passenger rail, so I decided to make my own. Drew them up on CAD at work and cut them out on the cnc plasma.

Re: 8.50 index build
 
At this point the front end was rebuilt as far as I could go for the time being. I was ready to start the tube work but was waiting for a bay to open up at work to get started.

So in the mean time I worked on building the rear housing. First was a mockup and measurements of the rear wheel/tire combination.

https://i.imgur.com/YpA55Hl.jpg

Then the rear could begin with welding on the 4 link doubler plates.

https://i.imgur.com/qDFyrs5.jpg

https://i.imgur.com/t2c6VSP.jpg?1

https://i.imgur.com/Tj9nKgE.jpg?1

Housing and 4 link brackets being fixtured up.

https://i.imgur.com/aWqOpn2.jpg

https://i.imgur.com/cFWV0hD.jpg

https://i.imgur.com/Xa8hdks.jpg

Once all the welding was done the housing ends could be fit which is a very time consuming/tedious process to get them perfectly square to the axle centerline.

https://i.imgur.com/rXmh9yM.jpg

https://i.imgur.com/0XJWY6B.jpg

A fixture was then made to hold the housing to the chassis table.

https://i.imgur.com/JSR2goy.jpg

About the time I was completing the work on the rear, a bay opened up at work so I transferred the car to its new home.

https://i.imgur.com/v9PsGOx.jpg

...and now tube work could begin.

I believe they call that rust trap you replaced a torque box.
Really amazing quality work. Might I ask what your line of work is?

I pretend Iím a chassis builder at work. Lol

Rocker/torque box was just one of several areas with rust. I kept cutting till there was no more rust. Lol

Thanks you. Doing my best to get this done in a timely manner, but still takes time. For the next few months it will be out of my hands waiting for body/paint, plus waiting to get the engine back.

Re: 8.50 index build
 
A couple key body pieces came in. The front end is carbon fiber from Motor City Solutions. The other piece is an original rear bumper that seems to be as rare as hens teeth. I'm converting the car from a 1989 areo nose to the 85-86 4 eye configuration and stock rear bumpers aren't reproduced and hard to find.

https://i.imgur.com/bZp4gWI.jpg?2

https://i.imgur.com/Q5A0U61.jpg?2

Oh yea, I forgot, the carbon fiber roof skin came in as well.

Re: 8.50 index build
 
Now was time to move to the front. First up was to tie the lower part of the front frame rails into the floor structure.

https://i.imgur.com/vdY4HH4.jpg?2

After that was done the engine & transmission were positioned so the midplate and motorplate could be fabricated.

Re: 8.50 index build
 
At this point the major part of the tube work was done and the body needed to come off long enough to weld any area not accessable with it on.

From here on out, the project was just working through one small project after another in which there were many.

First up was mounting the Racetech seat.

Thanks Jimmy. Trying to use what I learned over 27 years on the Malibu as well as advancing my skills over that time to make this car even better.

But the quality and work on this is no different than any other car we build for customers.

Stock shock towers as the class I run requires bolt on factory style suspension.

I work for a shop in Maryland called HFR Fabrication.

I think I can figure out what an 8.50 index class is but where does one get to race in it? How many times a year?

We have about 4 tracks in the area they will run 8:50 10:00 and 11:50 indexes. Heads up pro tree. Atco, Cecil, and maple grove are some tracks doing it. Also pro dial is becoming a popular class. If you notice all the indexes are right where the brakes for more rules are i.e. 1150 is the cut off for a roll bar. 10 flat is a cut off for a lot of the 9.99 Certs, and 850 is the cut off of many other certifications i.e. roll cage etc.
most of these classes do not include electronics either, I run the 1150 index with my street strip car and I know we are not allowed throttle stops or delay boxes. The class started out was supposed to be all streetcar as usual most of these classes have morphed into something a little different
