Default 90 caprice 305 tbi to 350 vortec swap
I have a 1990 caprice base sedan that came with the 305 TBI. I have removed the 305 but kept the 305 intake and kept TBI and put in a 5.7 liter 96 vortec engine. Will i have to change my ecu and wiring harness? And will i need a crank positioning sensor?

Might want to check but I don't believe that intake manifold will mount correctly to vortec heads. I could be wrong, maybe someone else can verify if I'm wrong about this.
