Up through a rifle drilled motor plate and hood scoop support and a pinhole sized orifice over each carb, glassed into the top of the scoop. Sounded like you could be looking straight at it and not see it.
When NHRA pretty much called the Gliddens liars when they explained how they did it, Bob said they couldn't find nitrous unless it was in a bottle painted blue. They proceeded to tech the crap out of HIM after that, seemingly in retaliation.
One of the Dodge pro stockers had a backfire out the hoodscoop the size of which most people said could only happen with nitrous. Next thing you know, their shop is broken into only to sledgehammer blocks, not steal parts. Many think they were caught and that this is the backroom deal that was come up with so the Dodge cars had an excuse as to why they couldn't run the E.T.s anymore instead of admitting to using nitrous since Mopar was a major sponsor.
I remember Buddy Morrison (R.I.P) saying something like "We're pro stockers. If we had engines that ran those numbers and you broke our blocks, we would have fixed them." (Heavily paraphrasing)
