Alright, I have a 94 lt1 installed in my 96 fullsize truck that originally had the vortec motor. I used a stock replacement vortec fuel pump with my lt1 swap (the vortec used 56-64psi fuel pressure) and have not had any problems. Will i need to upgrade the pump to something else or get an inline if I go with a standard 4.5-6# supercharger kit?
