1970 Chevy El Camino Restomod
Edelbrock and Throttle Setup
32- Edelbrock Setup-1 My original plan was to get the suspension in place, lower the car then work on the motor. However, I really loved being able to step inside the fender and work on the motor. Easier on the back and I could reach everywhere I needed to be. Therefore, I decided to take advantage of the extra space and do all the motor work before the suspension. Plus, I really enjoy the wiring projects more than working on suspension.
34- Edelbrock Setup-3 Everything passed the dry fitting. Valve covers fit over the rockers, intake matches the block. All looks good. Now it is time to prep the Edelbrock Pro Flo 4 XT multiport injection system for installation.
35- Edelbrock Setup-4 One of the complaints some people made about this system is that it lacked vacuum ports. So, I was prepared to run some T valves so I could connect the tranny line, PCV and Brake booster. I only needed 3 ports and from what I could read and see online there was two ports as shown in this photo. I also expected all the ports to be included, but this was not the case. So, I was off to the parts store to get several pieces I needed for installation. First up was a 3/8” vacuum port.
36- Edelbrock Setup-5 Next up was the addition of a 5/8” heater hose adapter.
37- Edelbrock Setup-6 In the front there are two open ports that I needed to cap. I bought one set plug and had a brass plug from the other intake that I reused. I should also mention that I using plumbers dope instead of tape on all these fittings.
38- Edelbrock Setup-7 After playing around with the throttle body I looked inside the system to see where the vacuum line fittings were sitting and I noticed a third hole in the far right corner. Wow, I was surprised. I could not find anything online that described this port hole, but it was capped. I removed it to install a 3/8” vacuum port and now I had the perfect port for the brake booster without running a T adapter. The other bonus is that this port is really built for the brake booster in mind. It baffles me why this is not described anywhere in the manual or online at Edelbrock.
39- Edelbrock Setup-8 On both sides of the intake there are these open holes designed for a throttle bracket or something like that. So, I just used some short bolts to plug the holes. These holes line up with a flat spot on the cylinder heads.
40- Edelbrock Setup-9 Bolts in place
41- Edelbrock Setup-10 The last step was to pull off the throttle body and install the thermostat and housing.
42- Edelbrock Setup-11 The thermostat housing was rubbed and painted black. Everything is setup now and ready for install.
