I'm kind of in the same boat as you.
I chatted with the SOVREN competition/tech guys earlier in the week regarding
placement of my TR3 in the grid. They basically said that if the car is built
to SCCA PCS - 1962 the car would be place into Vintage Group1. If the car was
built to PCS - 1967 or 69 it would probably be classified as Historic midbore
with the TR4s (I think Group 3 or 4; Jeff Quick or John James could confirm).
SOVREN is really trying to go back to the "Vintage Spirit" of authenticity and
integrity in preparation and good sportsmanship in competition.
I guess it depends on how forthright you want to be when filling out the car
information form and whether the tech guys would catch the upgrades.
The only problem I have with Group 1 is those f***ing Formula Vees. In the
March race at Pacific Raceways (in the downpour) the were almost invisable.
They sneak up on you in the corners and hold you up on the straights.
