On the air and gasoline delivery side of our Day 2 Power Parts Bolt-On for our '68 Mustang, Edelbrock, Quick Fuel Technology, Summit Racing, and Mustang Country send fuel to the fire.
Previously we introduced you to the ignition and exhaust side of our Day 2 Power Parts Bolt-on for our original, unrebuilt 289 in our '68 Mustang, check out the air and fuel delivery.
We're dealing with a small cubic inch engine with a low rpm range and low expected power output, so it's important to keep those thing sin mind to properly pick out parts.
For example, rather than an RPM or RPM Air-Gap manifold from Edelbrock, both of which make excellent power on modified engines, we went with their low-rise dual-plane Performer 289. That manifold is designed to increase horsepower and torque in the idle- 5,500 rpm range, which is where our 289's stock cam operates.
Similarly, we chose a carb from Quick Fuel Technology's Hot Rod series with a 580cfm rating. We've never ordered anything that small for an engine project before, but for our 289 it will provide more than enough air and fuel while still keeping the velocity high and throttle response crisp.
Since we want the car to have a Day 2 feel, but with better technology, we opted for an original 289 K-code style chrome open-element air cleaner filled with one of Summit Racing's high-flow reusable filters. This will give us unrestricted clean air for our Quick Fuel carb. The chrome valve covers are the matching 1968 high-profile style rather than the '67 and earlier low-profile since they are year correct, and will allow clearance for roller rockers.
