How do muscle cars get their choppy idle.Please explain as if you are talking to someone who has little experience with engines.
The camshaft causes the valves, intake and exhaust, to stay open longer. This increase overlap incease the flow through the engine. Depending on howradical the cam is it won't idle below 4k RPM and they produce so much less vacuum the power assist will not work so it cannot have conventional power brakes. Engine like this don't work below 4k RPM and reach maximum pwer at 8-9k RPM.
Not safe at all to drive like that

Yes - but only in the same way as you *can* drive with all of your lug nuts hand tight.

the choppy sound comes from a bigger camshaft. its also called a cam for short. you put a bigger cam in a v8 that has a bigger lift and duration and overlap. the amout of chop depends on the over lap of the cam. also you get more of a rugged sound with headers. theyre tubes that replace your exhaust manifold. they give it more or a pop sound.

comes from camshaft duration and lobe seperation duration of the cam is the amount of time the valves are held open. you want longer duration on the intake to provide maximum air/fuel mixuture to enter the combustion chamber. on the flip side, you have to get the spent exhaust mixutre out of there quick, in time for the intake charge. they open the exhaust valve a little longer on hot cams and the exhaust valve is open just a sliver while the intake is opening. this valve overlap is what gives you the choppy idle. edit: high lift doesn't give you the distinct choppy idle in muscle cars. high lift allows more air/fuel mixture to enter the chamber
