Steve - I was going to write a bit on the WC SV trickle down in the eighties, but the post was too long. It is a good lesson learned, and a good reason to have folks reason this stuff out carefully. It is probably the only case where a class of ex-pro cars was introduced into a lower class and then moved UP.
So, under the headline of those who fail to study history are doomed to repeat it, Steve, correct me where I'm wrong.
If I recall the history of FC, we started with tube-frame F3 based cars with a high-RPM crossflow engine. I don't know for sure, but those chassis could be FF, F2(FB), or F3(FC) just by changing the motor, brakes, and wheels, so I'd bet that when they got too expensive to run, guys converted them to FF (I know a couple of vintage FB guys who found their cars advertised as FFs).
In any case, the pro SV guys needed a place to get rid of their old cars starting with the move from 1600 TyIII to TyIV motors and the introduction of tubs in '72, so they were allowed into FC sometime thereafter (not sure of the date). Sometime after the rabbit cars arrived in '75, they were allowed into FC running carbs. Then later, the wheels got bigger, the 1800 engine arrived, and injection was allowed, and these cars were just way too fast for FC, so they were moved to FA, and I believe the older WC cars were forced to follow, because the current rules in FC only allow vintage FCs, Air Cooled SV, and F2000. If memory serves me right, these cars (Ralt-RT5s, Shannons, a couple of Marches, and Martinis) did OK in FA until the arrival of full-carbon tubs and the Toyota motor. But, if you had a flat-bottom, carburated, 1600cc WC SV with 6's and 8's (Ralt RT1s, Lolas, most Marches), you were pretty much hosed.
And the air cooled guys, well, you could spend a boat-load of money on new aero stuff and hand-grenade motors to run near the back of the F2000 pack. The best AC SV chassis technology was barely comparable to the early 80's rocker arm F2000's. The board never allowed good rods and custom pistons (all stock VW!), so you got the compression by flycutting the heads, which takes out the first cooling fin and causes the heads to crack - AND you had to do mickey mouse stuff like turning valves into cutters to make reliefs in the pistons, cutting rods in half to make stronger rod caps, etc, etc. Nobody was going to put up with that for long - and I guarantee you there are few truly legal Vintage air-cooled SV's (at least in terms of rods and pistons) because it makes no economic sense whatsoever. VARA recently split SV into three distinct classes:
1700cc air cooled non-winged chassis on treaded tires (essentially 1972 and earlier) FSV-1
1600cc water-cooled flat-bottomed chassis, and air-cooled winged cars with 2000cc motors (a combo never allowed in the SCCA) on 6s and 8s - FSV-2
Everything else: ground effects, injection, 1800cc motors, 8s and 10s, FSV-3.
Maybe the older cars do need to go away, for safety issues if nothing else (my AC SV is a deathtrap). But it should be done on a well thought out, scheduled basis with appropriate input from the affected parties, and not by decree from above.
My point in all of this rambling, and it's a little different than Steve's, is that pro trickle-down is a tradition in this class, BUT! It's been done badly in the past. The only guys that lucked out were the early FC/F3 guys that converted to FF (hey, that could still happen!). I remember a lot of butchered AC SV tubs converted to WC or with strange ground effects added. My '72 Royale was butchered up that way.
