It's a little known fact but Rich at HPH raced 1.8s as a racing platform for some strategic reason.
Class rules. The 1.8 was at the limit for some specific class in the SCCA--I think E Production or F Production. The engines were very much not stock, though. They didn't make much power below 5000 RPM, and red-lined at something like 7000. Mandated 40mm carbs, no FI allowed at all, headers were required to be at all competitive, and so on. They also used the "sewer pipe" cooling duct from the headlight buckets to the fan inlet, because ducting from the headlights was allwed by the rules. They ran fans that had most or in some cases all of the fins removed, and relied primarily on ram-air for cooling.
They made anywhere from 150 HP to 195 HP, and their lifespan was measured in hours. (In the less-aggressive cases, they could run a whole season before needing to be refreshed.)
Not stock or stockish motors, and very unsuited for driving on the street.
