If it's mechanical sec., yes they'll open at a certain throttle opening. If vac. sec., it's possible they won't open. On my 355s with Holley 3310s, the sec's will just barely open for a split second if you kick it hard to WOT. With the trans in neutral, there isn't enough load on the motor to need the sec's to kick in.
