Do i need a bigger fuel pump
 

i have a set of GT40 cast iron heads and a edelbrock performer rpm intake along with a wolverine blue racer cam.........but i have stock injectors and fuel pump.........do i need a bigger fuel pump or injectors and if i do need bigger injectors would 30 pounders be to much

Well with what you have I'd say your fine. My friend has the same set up as you do, but with a diff. cam. And still runs the stock fuel unit and injectors. With a set of slicks and 4.10 gears his pulling 12.78. You can go to a bigger more flowing fuel pump and 24lbs injectors, but you also have to change your mass air unit as it needs to be recalibrated for you injector size. 30lbs would to much in my opinion.

Unless you do more major mods to the motor, you should be fine. Same some money.

The 30 pound injectors are too big. You can support up to 350 hp with the 19 pounders. I would just go with the 24 lb. injectors. Plus, like St_Brawler said, make sure you get a corresponding MAF that's calibrated for the 24 pounders. C&L and ProM make them.

Your fuel pump is fine for now unless it's giving you problems (is it?). If you want to upgrade it go with at least a 155lph or even a 190 lph fuel pump.
