- The mods are usually based on *period* modifications, regardless of
- what may have been done in SCCA or other clubs at a later date.
- Production cars are almost never allowed on treaded tyres (same
- reasons). About the only thing on slicks are F1, Can AM, and later
- Winged Formula cars. (Plus some exhibition only cars) You will find
- some clubs which allow some more modern mods, but I beleive they are the
This is fine on easily categorized cars, like someone's old B/Prod Corvette.
It would fall neatly into B/Prod. No flares, street tires, no wild engine
mods. Easy.
Likewise on a repli-racer, an old car that fits the period but never
actually raced, like building an old Camaro as A/Sedan or building a Shelby
replica from an old Mustang.
But what happens to street cars that were modified back then into the
modified classes? Not everyone could buy a Corvette Grand Sport or a
Cheetah, but they could build a similar vehicle and race it in CM until '65
and ASR after '66. These cars could have flares, wider tires, wilder engines
(still in limited technology) then, so how do groups handle them today?
I'm also not talking about taking a nice old car today, modifying it to some
rules, and passing it off as a repli-racer for another class, like taking
'63-'67 Corvettes and adding Grand Sport body pieces to be a repli-Grand
Sport and run CM.
I'm talking about old race cars that really ran those classes.
- Most vintage clubs don't allow things like roller rockers, crank-fired
- ignition, belt driven cams (instead of chains), Stroked cranks, etc.
- Most clubs do print rules about such mods. Things like billet cranks
- are a bit harder to detect. From a reliability standpoint, I wouldn't
- mind on in my Frogeye, but not at that cost!
The cars I've seen that were not of '60s or early '70s technology in their
engines ran in SVRA, CARE, and SCCA events. They were not historically
significant vehicles, like Paul Newman's first car, or the winner of the
first Trans Am or such, but ordinary vintage cars that had raced SCCA club
events in the '60s and '70s. Yet Victor Jr. manifolds, fiberglass springs,
Wilwood brakes, Aeroquip plumbing, roller cams, fluid harmonic dampeners,
500 hp small block Chevies, are not '60s technology.
