It’s funny, at the end of the page you get the real story.
“Then, we have the MP cam. A stick with 20 degrees less duration would definitely help the fuel consumption situation” .
So we have a (presumably) 318 with 360 open chamber heads with a torker and a 750dp with a way too big camshaft that eats a ton of fuel. Yup sure sounds like Steve recommended a bunch of idle timing to crutch a shitty build put together by someone who only read the bottom of the camshaft page. A recommendation for MVA that is not. Moreso a recommendation to build better quality, more well thought out packages so you don’t have to do shtuff like push a bunch of idle timing to it.
