@imfealinghothothot , that's a relatively smooth-idling cam: on my SCCA GT-5 1200, I ran a 310 degree duration cam, plus 14:1 Cosworths....wouldn't idle well below at much less than 1500 rpm! On the dyno, uncorrected for 5000' air density, I saw a real 152 HP at the flywheel, at 9800 rpm....SCREEEAM, that lil bugger did!
I have got a very good hint for you to keeping the nice old Engine in good shape with todays ultra dry eco fuels: Use 1:100 API TC two stroke oil / fuel mix as regular driving fuel, that keeps the old fuel-system gaskets, rubber parts, alloy parts etc... and cast iron metal surfaces of those vintage engines in excellent shape...and it also lubricates the valves and upper piston regions. Most Porsche vintage owners in Germany do so :) Also keeps carbs and tank clean and rustfree
They have several names, known as bellmouths or velocity stacks or intake trumpets. They help improve the draw of air by smoothing it at the flared end. To buy them complete they can cost anywhere from USD $10 to $60 each depending on the shape, material and manufacturing process.
Generally they are used on sidedraught carbs or independent throttle bodies for fuel injection. Cars with downdraught carbs or single throttle plenum setups won't have them.
So often you see them because someone is running sidedraught carbs or ITBs.
Sounds great, I am putting these carbs on my 240z with L28. What are the jetting sizes? This will give me a great starting point. Thanks.

It's a double carburetor with double head each. This was before fuel injection.
