I don't know about a monster...... Iron Headed 410 CI only has 9:1 Compression on Pump Gas with a little bit of NOS!
The shifter will take care of the "N" Safety issue once its all wired up. I will be adding a Bosch Relay cause the "N" safety is + trigger and the "N" Saftey on a Mopar is negative trigger when using the factory Start Relay. Pretty easy to do.
I still need to build a catch can for the radiator overflow. I have all the stuff.... Just need to do it.
If I install the trans brake valve body I was told they will hit me for a Trans Blanket and an overflow catch can for the trans. I need to look into that some.
