Took my valve covers off over the weekend and it turns out this truck has had some good head work already done with some porting and bigger valves. It also looks like the edelbrock intake was put on just shortly before I bought it. I’m not going to do the 396 heads,roller upgrade, bigger cam and chip. I going to sell all that and go with a procharger. The new prochargers are a little pricey. They make them for the 5.7, 7.4, vortec and LS. If you don’t order the 600b procharger,you don’t have to run an oil line. The system actually adds to your existing pulley system so there is no extra crank pulley to install. At least on the 88,89 and 90 models with tbi there is no chip or programming of the ecu. You will get almost 600 horse and you can use your own high flow fuel pump and regulator that is supercharger sensitive. This system has to have an inter cooler that is included and designed to fit. You can also order the kit that adds the fmu fuel regulator and inline fuel pump.
