102+ heat and 45% humidity. What do you do to hook?
What ignition system do you have?
Most of the modern setups have at least a single stage retard. You can pull 8-10 degrees out at the hit for, say, .55 seconds then put it back.
It usually doesn't take much or for very long. I use a Mallory 685 box and I can do more than just that. And it if need more, I have severe Mallory 687 boxes with the controllers. MSD has similar stuff.
