hi,
for those of you that haven't ran across it yet, the legal GM s/s block has been discontinued and is no longer available. After a few emails back and forth and some discussion NHRA has made a decision to allow the 10185047 block. Here's their response-

I've also petitioned them to allow the new Dart SHP blocks because of price and availability, but haven't
heard back on that decision yet. I'll keep you posted.
