Side drafts

Dan, never much considered the HIF series, mostly because it seemed like they over-complicated the SU to make it more like a CD175 Stromberg. Mid 70's BL dreck. Always thought the HS series was the most foolproof. Not that I'm knocking the Stromberg, my 2nd favorite multi-carbeuretted DD was a 73 TR6 with Strombergs (1st favorite was a 71 Fiat 124 Coupe with dual 40mm IDF's, but that's another story).
