hey there guys i have a few ? i just build my first PP engine and i was wondering what size carb is good for it i have a holley 650 is that ok with a holley blue fuel pump. or i have a 4 injector throttle body with 4x1600cc inj just looking for info that guys

 

I personally would choose the fuel injection option over the carb option. Unless you are planning to run on alcohol or are going to turbo it, you don't need fuel injectors that large. Just out of curiosity, why did you decide to build a p port engine before you knew this?
