Starting from the passenger-side bolt farthest forward in the engine bay and work clockwise (in other words, map the passenger side front to back, then up the driver side toward the front), The front passenger side bolt hole is No. This will cause a poor seal at one end of the intake. You cannot simply go straight down the line and torque the bolts in order. There is a exact sequence required when torquing the 12 intake bolts on a 302 Ford engine. Keep in mind that the torquing sequence is just as important as the final torque value. On the 302 intake, the final torque value is 25 foot-pounds. This tool lets out an audible signal when the proper torque is reached, typically a clicking noise. On some newer models, the desired torque is set digitally. It resembles a long ratchet but it has an adjuster knob at the bottom where the desired torque value may be set. The tool used to assure a proper torque is applied is called a torque wrench. Failure to follow these values and processes can lead to damage to the engine block or intake, poor running due to vacuum leaks, or internal engine damage if debris is able to enter the engine. However, there are some components on the engine that absolutely must be torqued to specification by process. WhyĪll bolts have a recommended torque ratings, which are regularly ignored if known at all. Setting the intake bolts to the proper torque and in the proper order is imperative to prevent engine damage or performance problems. No matter what vehicle a 302 was in, the torque value and process were exactly the same. During the 1980s and early 1990s the 302 engine was commonly referred to as the 'five-point-oh,' or 5.0, though its combustion chamber displacement by volume was actually 4.9 liters, not 5.0. Hardened washers Must be used with intake bolts to ensure proper torque and prevent galling of the aluminum.Ford's 302 engine was a very common V8, available in many different Ford vehicles including the F-150 pickup and the Mustang muscle car. Use RTV sealant to properly seal end seals, such as Edelbrock High Temp Silicone sealant #1076, DO NOT USE END SEALS GASKETS. When using Edelbrock carburetors, use #1490 or #1845 throttle plate kit. Port exit dimensions: 1.09" x 1.84" Due to the design of Performer manifolds, the throttle and kickdown bracket on some vehicles may require modification to fit.
