Default Cam swap issues

I recently did a hci on my sbe 1s1.
build
btr cam
prc 243 heads
fast 102
granatelli 102 tb
lifters
pushrods
rocker arms
50lb injectors
all new gaskets and hardware.
i installed everything by the book measured pushrods torque specs u name it. Finally get the car put back together and i get 2 clunks from the engine bay when u turn accesorries on and reduced engine power immidiately and a ton of codes. So i strt the car and it sounds awful and stinks like gas and basically dies on it own. Its not tunes yet which i know would help but ive done this before and havent had this issue. Any tips or help would be greatly appreciated.

Needs a tune with that 102. That's where your reduced engine power and limp mode is coming from.

I imagine those 50# injectors are a big part of the problem as well....the stock tune will be dumping a lot more gas into the engine than it thinks it is.
