Darn, it's another Digest Delayed Response. Are we still talking about
Vintage? :-)
This is very similar to our local Vintage class. And it's a terrific idea.
We use the phrase "period correct" to limit things like MOTEC Injection or 9
inch wheels on your MGB. If it didn't exist then, it's not allowed now. We
use 1975 as the limit (1973 cuts out the 260Z for example.) and have just added
the verbiage to allow "substantially unchanged" to deal with models that
continued past that, ala MGB, Spitfire, even some TVRs :)
Kudos for including the camshaft allowance, that is one of the most important
changes that we don't do anymore.
One nit: You will be hard pressed to get ANY CamaroBird or Corvette to
participate with a 7" wheel limit. They've been running beyond 7 inchers
before I was born, the '73 'vette had 7.5 (maybe 8)inch rims.
(PS I'm a liar! Maybe its 2 or 3 nits...and I was in college in 1973:)
For cars that were not Stock back then, fender extensions were pretty popular
on some (Datsun 510 BRE styled, mostly) cars that may be common, and you'll
find any number of higher compression pistons or heads used to take best
advantage of the cams... that poor '78 MGB just isn't going to make it with
it's 7.5/1 compression, and again the GM cars(and even some TVRs:) will hate
you for tempting them cams but no compression changes.
These are mods that may go beyond today's preparation standards but they were
the basics of increased speed in 1973. MG, Triumph, Datsun, Cameroon and
Corvette are easily 90% of the market for non-Stock vintage, since that's what
there was then, so don't discourage them.
911s are the other 10%, and they don't need any help...
These are only nits if your intent is to encourage these vintage cars to
compete as they may have "back in the day".
If your intent is to give people a chance to run their garage queens without
harming them, then nevermind...

PS I would break out the 4 and 6 cyl. TVRs to V3, and V8 TVRs (all 3 that
exist) will do OK in V1.
Now I'm done. No really, honest, I promise...

Subject: Proposal for vintage-oriented autocross class.
Here's a copy of something I just sent to the SEB. It's a proposal for a
regional-optional vintage autocross class.
Dear SEB,
Grassroots Motorsports has long been a supporter of the national Solo II
program, with pages of editorial promotion for all of SCCA's efforts in each
issue. As you might be aware, our latest venture is the launching of a new
magazine for the U.S. market, Classic Autosport. The new magazine will be
using British Car magazine as a basis and expanding to include marques from
countries other than Britain. Classic Autosport's goal is to become the
nexus for all classic sports car activities in the United States.
We'd like to suggest that there is a large market of sports car enthusiasts
that are interested in autocross and road-rally type activities, as evidenced
by the numerous classic marque clubs that hold autocrosses, yet aren't really
ever seen at local SCCA events. A few classes for vintage cars at local
autocrosses (pre 1973) could do for this crowd what Street Touring has been
