As a new guy here (but long-time unregistered lurker) and fresh owner of a "belly tank" (as of 1pm this afternoon!) I completely get what the OP was talking about.
Maybe that's because I can also see the difference between "Vintage gassers" and modern gassers and "vintage Front Engine Dragsters" and modern front engine dragsters without shooting someone down on little more than semantics.
The OP was talking about a sub-category for tear-drop shaped Lakesters and streamliners, so that they aren't forced to compete against Cigar Tube Lakesters and Streamliners.
If someone is building a vintage-appearing gasser to race (or restored one from the '60s), it's got modern safety equipment, probably a modern engine, but no electronic delay boxes, it sits nose-high with a tube axle, and has period-looking wheels and paint, and no aero.
Modern gassers are slammed, have aero noses, modern scoops and often rear wings, and modern paint jobs. While the nostalgic body may be a '41 Willys, it sure doesn't resemble the car Stones, Wood and Cook ran.
Guys building the modern cars don't care about the guys building the vintage style, and tell them "If you want to be competitive, then build a competitive car."
Guys who like the old stuff want to race against like-minded individuals with similarly styled, technologically-similar cars.
I found some of the posts here interesting... guys talking about how they like the open rules and don't want to be hemmed in by sub-classes, and the general feeling of "if you want to be competitive, then build a competitive car" when some of the records are over 300mph.
But it's obvious SCTA has seen a need for these kinds of changes in other classes, hence the Classic category for the door-slammers, and the V4 and XO classes...
Otherwise, the guys who wanted to be competitive should have built competitive cars... they shouldn't have asked for dedicated classes to run their pre-'80s body styles, or their flat-head 4 cylinder engines... I mean, there are already engine classes covering every displacement... if someone wanted to run an antique 4, then that's their problem. They should have just sucked it up and gone out for fun, rather than ask everyone to cater to them.
Right?
(and while I'm on a roll for my first post... how much of an affect did opening up new classes and niches have on Land Speed popularity, interest and new builds/competitors?)
I'll shut up now.
