I know a few people here watch Harry's garage, he didn't awesome series a year or so ago about have the engine rebuilt on his Lamborghini Espada. Now he's having his Lancia Fulva Zagato done. I knew they had a relatively narrow angle V4 but never knew much about it. The current episode is the strip down. Look at this engine, it's beautiful. Narrow angle V4 long before the VWVR6. 110-ish (Optimistic Italian) horsepower around 1970 for 1.3 L in a car that cost as much as a Jag E type. All of the engine routes go back to the 1920s. I have a new rabbit hole to go down. Here's a couple of screenshots of the head and the deck of the block, best I could get on my phone.
