Fresno is centrally located for both Famoso, down in Bakersfield, and Sacramento Raceway up north. Check out A.N.R.A. They run a brief series of races at Famoso with bracket (timed launch), and A-E gas. E-gas being a 11.6 index. If your car runs 12's or slower, you could run in Sportsman Bracket. Faster than 12, then you would be in Hot Rod Bracket. Also, they run nostalgia front engine classes, and open wheel. Lots of fun. You can also do test and tune races at both Famoso and Sac Raceway. They have an annual New Years race up at Sac, for a winter fix! Both are drivable in one day from Fresno, as you know. Your car is older than '73' so you can run in ANRA. I think your car has a BBC, so you have lots of flexibility for what classes you could run.
Tech is not to hard to figure out. Get an nhra rulebook. PM me here in FAT.
I know a guy here that is a tune wizard. Get your wallet out though!
