So here's the questions as I'm going E85 straight from here;
If I change these 2 pulleys which I've seen some people do and pulling 650-700rwhp, what Belt will I need to run? - https://www.summitracing.com/int/par...-300/overview/

Also, has anyone upgraded to say a Nismo oil pump/aftermarket pump and raised rev limiter? |
Stock Gates 8PK562 will be OK but you may experience a little bit belt slip under high engine RPM (starting from 6000). Getting a 36225 3" idler will be better. Or you can use RPM belt but it will be more brittle. The degree of slip depends on the setup of preset boost. The higher the boost the higher the chance you encounter belt slip.
