It should be high 13s already. You could do headers and performance heads and that would probobly put you at high 12s. Alittle more money and you could put a 6 PSI super charger and go low low 12s and with headers probobly high 11s. But get slicks.. You will need them!!!!!!!!!!!!!!

Well my buddies 96 z28 went 11.60s with the stock pump. Gotta love nitrous. With engine mods ( other than nitrous) that fuel pump would probobly take you as far as you want to go for a street car. It would probobly be a good idea to put an adjustible fuel press regulator on it so you can turn the pressure up. The stock pump is capable of 100 psi and any fuel system you put on the LT1 wont require near that much press. If you put really high flow injectors or a supercharger or something big like that then i would put a booster pump on it. Most of the supercharger kits come with a new in tank pump though because the stock pump cant flow enough. Has the press just not the flow capacity. i would say deff low 11s with the stock pump on a naturaly aspirated LT1. Oh yeah i love GNs. Three of my friends have them and they are BAD!!!! One of them runs low 11s and two run low 13s. Not much done to them. I still will stick to F bodies though.
