I also posted this in the fueling and injector forum part, but thought id ask here also. I recently got some 30lb red top svo injectors. Im going to swap them out with my stock 02 camaro z28 ones. I was talking to a buddy of mine and he said he doesnt think i need more fuel, then he said i might need a new pump and rails to feed it. What do you guys think? My current mods are...torquer 2 cam, 5.3 ported heads, ls6 intake, ls7 lifters, hardened push rods, .650 prc double valve springs, slp cai and lid, blackwing air filter, pacesetter lts, tsp true dual x pipe to dumped bullets, hp tune. Im also getting ready to put in an ls2 timing chain, slp 160 thermo, slp ported oil pump, asp underdrive pulley, and going to pull out all a/c stuff. Let me know what you all think, thanks.

Upgrading to a walbro pump will help later. But you do not need to change the rails they will be fine.

upgrade the pump. or get a tech 2 scanner on there and check out the fuel trims.

stock fuel rails will work fine
