I plan on doing a cc 306 or a gm 847 cam on some P&P heads. My question is that I have a 93 and I was wondering if I need bigger injectors to do the swap? I live at high altitiude (5280ft-5800 ft) if that helps.

 

Depends if your gonna get bigger valves, run nitrous,etc...

 

I plan on adding a fuel pump, the heads will have bigger valves (they are stg 2 heads), and I might run nitrous. I was wondering since I live at such high altitude that I could get away without getting injectors.

 

Personally, I would get bigger injectors..like 30#'s, and adjustable fuel pressure regulator..You should be fine.

 

Get the injectors. Why would you risk melting down an engine you just spent several thousand on because you don't want to spend $200 on a set of injectors?
