So I've been reading build treads and looking at parts I have and how they would work together. I got on Wallace calculator to see if the experts were right that helped pick the parts for a build I'm planning. Also so I understandi what I'm looking at, hearing and reading.
So where I got confused is inlet valve closing ABDC on the calculator. I found some math that I believe gives me that °. Using my cam if correct it goes (291÷2+110-4-180=71.5°) . Now that 71.5 seems to be right or am I wrong and the number is 56.5° because this is the ABDC number . This number does not look correct when used. Some clarification would be great
