At what point does the stock fuel system become a restriction? How much power can it support and what's a good upgrade? I just want to know for future referance. Thanks.

 

typically, the stock fuel pump can hold any kind of head/cam combo yo do. i'm pretty sure the fuel pump is rated to 450 hp. the injectors, however, don't quite live up to that without overloading the injectors. usually, u can use stock injectors on cam only cars, and some lighter head/cam cars. to be general, good modifications are 30lb inejctors and a walbro 255gph fuel pump. obviously, depending on your application, you choose injector sizes accordingly.

 

The lines and rail are good to more power than most of us could hope for with the lines giving in first.

 

That's good news. I figured it would be a nightmare.
