408 Stroker
Hi, I have a 426 SB stroker set up for street use. My recommendation for you would be to go for the roller cam setup since you tore the engine apart already, as well as fuel injection.
Keep in mind that since you are stroking a SB everything that you put will be undersized, this means the intake, cam, etc. you need to go one or 2 steps beyond what you would do in a standard small block simply because the stroker drws more air into the engine.
For fuel if possible I recommend you to go EFI sniper or the edelbrock pro flo will do the job.
Compression depends on what heads you will be using. I recommend to go aluminum since this will save you front end weight as will do the aftermarket aluminum intake. Try to get forged internal but not heavy parts like eagle rods or so, get them as light as you can by design. Molnar HW is excellent.
There is abook calles big inch small block mopars I believe which has very useful info, pictures and tips for a mopar stroker build.
I hope the info helps.
