Re: What Radiator ?
If yur looking to get rid of the fitting here's what I did. Go to your rad shop and get a rubber cap. (Don't know if they're available at any AP store.) Slide that thing on and clamp it. I then drilled and tapped a hole and installed a fitting in the top of the WP. Like most Edelbrock pumps but free except for my labor. Works great and my turbo intake just fits.
