How to achieve this stance please?

So I dont even own it yet and I'm already planning changes :D
The car has factory 15" steels, so I'm planning probably 225/60/15 as a step one, unless you tell me I can go bigger at the back?
I´m guessing the factory wheels are 15/7"?
There seems to be a fair amount of space between the wheel and fender at the moment.
Step two are new leaf springs with at least 2" lift as the back seems really low.
Superstock do seem a bit of a overkill for 318 with standart 7 1/4 rear, so is there tested middle ground for the springs lift?
Then lifting the front about an inch to give it some rake.
The red Scamp on the pictures is what I´m looking for in terms of stance.
Many thanks!!

Some young fellas in a small town in Saskatchewan, Canada were into street racing Mopars. One had a Duster 340 with 4 spd trans. He got ahold of a narrowed rear axle for it. The car sat level like off the showroom floor. Another young fella in a small city an hour away had a Charger 440 with a GMC 6-71 blower on it and the rear lifted to clear wide tires. Much more rake than the red car. They arranged to race as this Charger was supposed to be fierce fast. Loaded the Duster on the equipement trailer in case something broke and drove to the city. Someone flagged them off and they both hammered the throttle. That 440 could not hook up and transfer weight to the rear tires for traction. That 340 just squatted the rear and took off. The Charger was only half way down the 1/4 mile while the Duster was slowing down. It would only do about 120 MPH but gosh it got there fast.
These guys built their engines in the barn, of all places. They blew a bunch up from missed shifts at 7500 RPM with stock conrods.
