You’re making awesome progress, stay with it.
Put this in it.

Looks like you are getting it well braced. Good job.
Working on the firewall today. Here is a pic of how the console is all tied in as well.
I guess I could, hadn't thought too much about it. Stock cars don't seem to, the fast high hp drag cars do. Hmmm

Safety first. Without triangulation it can flexat speed. Big bang theory follows.
In a similar vein, consider like the Shelby Monaco? brace that bolts in to keep side to side movement under control.
I would need to put the motor and trans back in to verify clearances. .
I believe it is a very stout cage and frame. Frame is 2x4x3/16 with double frame in drivers compartment. If this thing flexes, I am in deep **** anyway. I will look into triangulation. The plan is for bolt in cross bracing (side to side) but that doesn't fulfill the triangulation.
It doesn't seem like I will be able to triangulate in the front. The front section, yes, the middle section will not allow the suspension to be removed or installed, and the rear section is where the headers pass through.
So I threw the motor back in to double check everything.

Can you triangulate off of the coil bucket?
And if something needs to be removable you can use bolt in tube clamps.

I need to look to see if there is a way to do that. The coil/strut has studs in them. Not sure they are long enough. Will have to study options a bit. I agree triangulation is ideal.

What about gusset the joints? Not the same as triangulation, but could stiffen some.
Another concern can be crash G loading getting transferred to the driver. Part of the reason new cars are written off so much in apparently not that serious crashes is the impact absorbtion structure. The first few inches bends relatively easily, while becoming stiffer as the structure is bent. NASCAR incorporates this in their cages. That upper bar coming off the front upper of the firewall has a curve near the front as it bends down to be welded to the front frame rail. In a NASCAR superspeedway crash, the speeds can be 200MPH with collisions with other cars or the wall possible.
Now on the salt there is not much to hit beyond the timing sensors. Getting airborn is a possibility, which presents impact with the ground as the immoveable object that causes damage.
Just something to consider with input from the tech guys. On SCTA/BNI safety, I am not an expert by any stretch.
I started making up the cross bar above the radiator mount. The bar is made and gussets are just tacked for now. 1.75 DOM with threaded bushing insert and 5/8 bolt on each side.
Lordy. What's your target weight, 3 tons? lol
Well, at Bonneville, due to lack of any traction, weight is your friend. 4-6000 is very typical for even a Camaro
I put the radiator back in to mock up the side closeout panels, mount reinforcements and front crossmember.
Yeah, I knew they weren't lightweights.

Weight on the salt is good. The salt can be a bit damp, especially early in Speed Week. It is also grainy like sand. Combine that with narrow tires for low rolling resistance, you require weight.
