Can i run 8lbs on a stock fuel rail with 390cc injectors?

 

I'd go at least 440cc just to be safe

 

psi is irrelevant in what injectors to be running. You can run a stock fuel rail up to i believe 400whp then you need something but you might be able to run more not sure. But like he said gets ome 450's or 440's there cheap and good for 300whp range
