Yes it is !!!!
Did you dyno on race fuel or pump gas and still with 39 lb injectors? I have a similar build in progress but not exactly the same on approx. 11.4 compression and just mild head work. I'm using 42 lbs injectors when its done.
I believe 93 and yes just 39# injectors.
What intake are you using?
What's your goal horsepower?
