The 3B has a pretty good running fhead, but we are going to see how much better it runs, if at all, with fuel injection. In reality it probably does not need it, but i like fun projects. it uses a 1barrel GM throttle body, from the late 80's 2.5 iron duke 4cyl. These old TBI systems are super simple, bullet proof and easy to dial in. The stock distr needs to have a electronic pickup installed and the weights removed, as all the timing will be done by the computer. I used a new replacement electronic dist, so only the weights were removed. I got the harness, adapters and computer from Hamilton FI, so after its running, we will datalog it, send the data over the hamilton, and they will update the chip with engine specific programming. I am getting close to startup, elec fuel pump, filter, all new feed and return lines are installed, temp sensor and O2 sensor are installed, and stock linkage is connected to the TB Im using the stock tank, and feeding the return in from the bottom drain fitting, hoping it will work, otherwise i will have to install a bulkhead fitting on top of the tank and route the return there.
