Vortec is a total useless piece of junk. Instead of using a fuel rail it sprays fuel into the cylinder with plastic and rubber lines. Heat makes those things brittle until the supply line busts and dumps large amounts of fuel flooding your engine. The next thing you know you are replacing an expensive piece of rubber, replacing a ruined cat and draining gas out of your oil pan. You can have your Vortec.The 91 Chevy is not a Vortec... there's quite a bit of power difference. The Vortec was used from '96 to '98/'99.
