If anyone seriously thinks that the rego nazis will limit a blown big block Chev to 9lb boost, just because it is in a pre 1949 car, but happily allow unlimited boost in the same engine when it is fitted to a post '48 car, i would suggest that you ask yourself if you really think that they are actually that stupid.
the NHRA and the RTA have been working very close with each other on this legislation.
i believe the act you are referring to is to do with reproduction chassis and bodies and pretty much anything with a 'glass body. what they're trying to encourage is original bodies on newer and better designed repro chassis.
the maximum engine size for a "hot rod" is 460ci under the new rules, which includes a turbocharged engine with a max limit of 9psi on a 351ci engine. any more than 9psi and you have to reduce the engine size accordingly, but this sliding scale isn't available yet.
note the ford ci sizes there, their equivelant chevy engines are smaller (454 and 350) but the same rule applies.
you could always declare a 351ci engine with 9psi, and then turn it up for the track, but 9psi is the limit for street use.
so, 20psi on your A14 is perfectly acceptable.
sliding scale, remember.
