100 shot of nitrous on 360 magnum engine

I would strongly suggest that you wire in a NOS mini progressive (about $200), if anything for the RPM window switch capability. Add a WOT switch between the controller and the activation button for the kit and you will be good to go.
That's what my machinest said too
He said controller to dial back timing
He gappped my rings for it and said don't go crazy you will be fine.
Was also told run a dedicated pump from a small cell with high test fuel like 110 with lead to feed it.

My 2 plates for front and rear carbs of my Holley Cheater have small jets and work up. Has 3 levels of jets. Note) Center carb gets no plate, it gets spacer since you are only using it under WOT when the outboard are open.
