I’ll say the casting inside the runner was a little ruff. The runners are more narrow than a RPM. Ports were uniform at there exit at the head.
The exterior was nice. Nothing looking like a second rate POS. The bolt holes lined up well. This is on a uncut deck 360. They mated to the Edelbrock heads without any issues. A standard Fel-Pro gasket was used. I don’t remember the part number, sorry.
Since the intake is dual drilled, the included hammer in, interference fit plugs were a good tight fit. The intake was also packaged with Allen head plugs that took care of the extra drilled and tapped holes. Everything screwed in well. No drama.
Overall, a decent part and the price was right.
If your looking for a maximum return for best power results, use the Edelbrock RPM series intake.
