They haven`t made an engine with a carburetor in about 35 years neither, do you suggest all older Stockers should be allowed EFI as well? Also been over 20 years since Chevy built a non LS small block, do you suggest LS engines for old cars? I personally believe that NHRA has allowed far too many superseded/approved/updated parts to the "STOCK" class, be nice if at least some semblance of "STOCK" components remains, before it turns into an anything goes bracket class. If you just have to have a roller cam, there are plenty of combinations that came with them from the factory, to chose from.
