That makes sense. Connecting the dots..........

By the way Gene, you're a cool dude!!!!!

Cool thread there !

Here's a cool pic of the side exhaust's. The individual runner inatke set up even makes it even cooler. LOL.

The Patterson side pipes were symmetrical. Bob only had to design and build only one header model---they would fit on the left, right, front or rear. Did require tailpipes of different lengths, tho---

Gene knows that boat very well, that's Aeromarine III in a later life.

There pretty! That's what an engine room should look like!

Hilborn stacks are badass.

Those are Kinsler-Lucas units. Hiborn were constant flow.

Right on, what type of metering did those use? Like a throttle valve or something?

Lucas made the fuel metering unit. It is usually driven from the Cam replacing the distributor. Some had a right angle drive to run the distributor. This puts a little more torsional load on the cam and also puts more load on the timing chain.
Some Aeromarine engines had special front gear drive setups that also drove the metering unit.

Think of the Lucas metering unit as a fuel distributor.
The output at the injector is timed or pulsed as the metering nozzles spin in the housing passing each injection port. The faster the engine spins the more net flow you get. The fuel output is also multiplied by the throttle position with a mechanical linkage from the throttle shaft to the cam linkage on the top of the metering unit. Think of it like a vacuum advance mechanism.
These were the hot ticket back in the day and I believe Lucas had a patent on them.

Richie Powers adapted them for marine use when he worked for Kiekhaefer.

Awesome information. Kind of like an early mechanical sequential fuel injection.

Thanks for the input.
