Trying to set stroked yblock motor up to 4r70w trans. I need to find a Throttle Position Sensor that will work with a Summit 750 electric choke carb. Called Summit and they said they did not have one. E mailed tech help and they gave me a part for Holley carb. I have seen units for Edelbrock, Holley, and others. If anyone has run this carb with a TPS, what did you use and did you have top modify anything to make it work?
