Dates do not totally conflict. Tulsa dates are June 18-21 (Thursday – Sunday), while SAAC-45 Indy dates are now June 17-19 (Wednesday – Friday). Because they are fairly close geographically, it looks like that given some official scheduling cooperation, it would be possible to accommodate particularly the Concours Judging (typically one day) so that an owner could make both events. This could also work for the general car show participants as well, which is Sunday in Tulsa.
How about exploring some cooperation that might benefit the car owner, while really not detracting from either event? Have your cake and eat it to, with a little interstate on the side?
