Justin, your plans for your race would fit into the NHRA Heritage 7.0 Pro, or NE-1 [ 7.60] classes. Check the Heritage web site for rules.
It's just that unless Steve Gibbs can sell a Heritage event in Spokane, you will have to travel. The closest is Salt Lake City [ 2 back to back events] 720 miles, next closest is Sacramento, 820 mi, and of course the big nostaliga races are in Bakersfield, 1100 mi.
But you could race your combo in Top Dragster, ya I know the real fast guys run in the low 6's, but if you race Div 6 events you may not run into many real fast guys, besides you pick your dial-in. Check the NHRA web site for Div 6 races, 280 miles to 425 miles from you, besides one race in Spokane, two races in Woodburn, Or, Seattle, Mission B.C., Boise, and of course the NHRA National in Seattle [280 mi]. Your combo will not fit into any Comp class, but if you build your FED blown Alky BBC you could race Heritage, or Top Dragster.
BTW Gary Adams,[ Gene's brother] lives in Spokane and he is always working on getting events for nostaliga A/FD, like they will have a booked in A/FD show in Woodburn this year. You might be able to run with those guys. How far are you willing to tow ?
I don't know about Spokane Super Pro, or Pro, so see how your race car would fit into these classes. Also talk to other racers to see if you could get a Heritage type group together.
