Stock block but I did upgrade the fuel system a little bit. Put in the JHM 255 lph pump and high flow filter just as a precaution but I didn’t have to. The injectors get upgraded with the supercharger kit because they have to be.
Quintin/q_dubz has not gone faster than what I have run years ago and he did change his fueling. He ran one time and made excuses rather than run again to do better. I don’t think that he wanted it bad enough or the car wouldn’t actually perform.
The JHM supercharger kit is the most reliable and best performing kit out there with both Axel, other guys, and I putting a ton of miles on our cars. Can’t wait to see your car with the supercharger installed!
