A few years ago I picked up a complete TPI unit off of a 1988 vette. Has long water neck, all injectors, egr valve, fuel rails, pressure regulator, plenum, throttle body, metal distributor cover, and computer HEI with plug wires. All you need is a wiring harness and computer from a '88 Vette or do it the right way and get the harness and ECU from a 89 or newer Vette and go speed density instead of MAF. Replace that TBI or carb and step up to the best intake system ever for the small block chevy. I paid $350 a few years back so I am asking $350 or will take any reasonable offer. Feel free to text me at 586-214-9989 Thanks.
