I think the ultimate flathead Ford would be the french military flathead - Google Search. It's basically a 49-53 block with an early bellhousing.

XF are old flathead motors. /BGC is Blown Gas Coupe. Couldn't find much on the web about the car other than he set a couple records with it this year.

Similar to the yellow Corvette (?) above..

If you strike out with the belt material you might check auto parts stores for a medium-density polyurethane foam floor pads.Over here,they come 5-panels per package (610mm X 610mm) for around $15 (US).
I've used the same foam on my truck at least 3-years now with little degradation.
At 75-mph there is no deflection,while if I hit a curb they just bend under until I back away.
Kind of a medium-gray color

Interesting thought, I have a few lying around - the ones I have are pretty thin though, maybe 6-8mm IIRC? I would have thought it wasn't rigid enough - how thick are the ones on the truck?

Conveyor belt or baler belt material is a good choice as well. McMaster Car, Tractor Supply, Grainger, etc.

I have a roll that I was going to purchase from Speedway, but found on Amazon for the same price, with free shipping. However, it arrived, and I realized that I would have much more work than I had anticipated--it is a 24" roll. Can I just cut it to length and nail it to my bumper?

Without actually measuring,I'd guess that they're about 13mm.
One side is smooth,the other is a star-plate pattern as you might see with aluminum pickup truck tool boxes which straddle the bed rails.(CRAFTSMAN/TRACTOR SUPPLY)
The nose on the T-100 is 'oval',almost a semicircle in plan-view,which gives a lot of rigidity without any reinforcement.

If you can rip it down to size I think you'd really like it.Big Dave came by a few moons back,and his conveyor belt air dam was awesome.When hell does freeze over his air dam will still be going strong!
Would a bandsaw do it?
Big Dave,any advice?

...a steady hand and a reciprocating saw will work wonders.

I have thought that I could screw it to a 2x4, with a 1x1 on top, use the board as a guide, cut it with my circular saw, and then mount it with the same screw holes.

If it doesn't cooperate put a cut-off wheel in the circular saw.
