    1994 TBI 305 to 355 TBI Upgrade

    K so I decided to go a different route and am Buying a 350 TBI bored 30 over complete oil pan to valve covers minus intake. I plan on putting an Edelbrock 3704 intake on it and my Throttle body with a adjustable fuel regulator from Jet. My TB seems to have orange injectors in it so thinking they are the 350 injectors.. Not sure why they are in it but figure I would try them out till I can Find red ones. Im told the Knock sensors are different and also go by displacement so would I go with just a 350 sensor or would I need to find one for a 355? Also will I have to tune it in order for it to run right? I Downloaded the program to tune the ODB1 system but still need to order the cable. Just wondering what else I will have to change so I get it all set before running into issues. I plan on dropping the motor in the truck in the next couple weeks. Fast355 whatever information you have is always appreciated.
