My dad is restoring a 57 chevy for a guy and he just brought over the frame and drive train today. Well im not sure of the different years of the vortec but it looks exactly like the one in our 98 Z71 silverado. Now all he has is the motor with all the sensors and the painless vortec wiring harness no ecu yet. I want to be able to tune it and remove the egr and some things but I have a v1 and I dont think it work with the 98 style vortec computers. What would you guys recommend is there a ecu I can buy that will hook up to the vortec harness and work with the V1? I can take pictures tomorrow also. I tried to talk him out of it for a TPI intake the vortec intake is fugly.
