OK, a "Rice Rocket" is a motorcycle. A "Rice Burner" is a car. Just to be P.C.
The real answer is; "Why should they work on one of those under-powered, poor handling, hot, noisy, smelly, non-air conditioned, gas guzzling "Street Rods", when they can run a 4WD Mitsubishi or WRX Turbo running over 450 HP (to the WHEELS!) that handles damn close to a FIAA car, can EASILY out-run a Cobra, Corvette C5 or Viper both at the drags and on road courses (I've personally seen Eclipses do this on a regular basis - and the EVO's are coming on strong) and are absolutely a joy to drive around town - tame as hell until you get your foot in it. AND, they get way better than respectable mileage - 20's and up!
I've driven Deuces......NONE of them handled worth a damn, and they were REALLY scary over 80 mph (especially when you could look down and see the road going by).
I've watched my son and his friends working on their "Rice Burners"......Eclipse, WRX, Toyotas, of all types......some of these guys can pull in to the garage Friday night, do an engine pull and a tear-down, install lots of mods and rebuild, and have it ready to go to work on Monday morning, then drive it to the Drags at Epping (N.H.) on Wednesday night and repeatedly dust off Corvettes, Mustangs and Vipers and then DRIVE IT HOME! I used to tag along with my brother's friends who went to the Epping drags in the '60's. One of them had a '62 409 and he did well there in his class, but you could never drive it to/from the track with the drag gearing he had in it.......4400 rpm at turnpike speed for two hours+?? Don't be ridiculous!! We had to TOW it there and back!
When I was a kid (50's and 60's) I loved VW's because they were (are) easy to work on and they were CHEAP. I built 8 dune buggies and never paid more than 50 bucks for any of the donor cars (with engines!). Building up a stout 1915 with a single Holley 450 cost about $750. When I built Pearl, I paid $350 for the donor and thought that was cheap, even though I threw out or gave most of it away, and I think I've got $5K into my engine. When I started on my '46 Ford coupe (1970), I bought the donor for $125, with a .230-over 59A/B flathead engine already set up with lots of race-goodies. Doubt that you could touch one for less than a Grand or two these days, just for the engine (I sold just the engine in 1982 for $750).
So what am I saying???? THIS generation of "Street Rodders" is doing the same thing we were back in the '60's and '70's; finding cheap iron that is strong and easily built into massive, reliable horsepower, BUT, they're putting that power into a chassis that handles like the hammers of hell. Most of you have never driven a turbo'd, 450+ hp 4WD Eclipse. I have - Chris' "Eclipsecicle". Believe me, around town it is the most well-mannered car you've ever seen. That same car, out at the drags, eats C5 Corvettes by several lengths turning mid-low elevens, and on a road course, they wouldn't stand a chance. I've NEVER driven a so-called "Street Rod" with that kind of power, ever.
A well built, 450+hp Eclipse, EVO or WRX can be built for way under $30K BRAND NEW, AND be driven to work and to the store. Starting with a used one would more than cut the cost in half.
A well built 32 Deuce around here, built at home, will probably cost you upwards of $40K unless you've got very generous friends (and they're out there). You could never easily drive it to work or the store and forget about having a passenger and then adding groceries or a cooler.
Why would young kids today want to build a Deuce??????? Obviously, they don't. The guys who will be buying them (already built by someone else) are the Baby Boomers who already have more money than they'll be able to spend in several lifetimes, and they're about to inherit MORE from their money-saving parents when they die.
