So, here's my nitrous 318 Drag Week adventure...

Mopar crate
15 in. Tires
Magnum roller
These 3 answers need some clarification.
Which MP create? But it's the 380 as stated correct?
You don't have 15 inch tires. You have 15 inch wheels. Basically useless info. The tire size is missing.
The cam description leaves several cams to choose from mopar. And many other manufacturers.
Can I assume it is the cam that came with the create engine?
