i ran a 500 + hp 406 for over 10 years with the stock fuel system and a good pump. you have either a restriction or air leak somewhere in your system. gm sells a nice hv fuel pump that will feed all of the engine you can build.take the sock out of the tank and use a large inline filter ,replace all of the fuel lines with fuel injection hose .its heavier hose and wont colapse at high speeds like regular hose
Fuel delivery issue

So my car didn't perform like I wanted it to in Belton due to it falling off at 4500 rpms from not getting enough gas. I race this car and get down on it a lot since its my daily driver but never has it acted like this. I rarely hit 4500 rpms on the street or just with everyday driving,but could a high volume fuel pump be the fix?
My engine can put out way more than what it is now,so any pointers are appreciated.:beer:

gm sells pumps that runs 7 and 9 psi for use with and without regulators. i prefere mechanical pumps over an electric because of the electrics nature of failing without much warning
i use the gm #12355612 any chevy dealer can get for you it flows over 100 gph at 7 psi
