Replace head type and dome cc's with cranking compression psi.
I need to know head type because if its stock it uses a default variable. If its not i need to know CC's of the dome to accurately calculate the cylinders total volume. (air/fuel ratio). With the dome size and stock head == false, along with bore and stroke i can calculate the cranking compression.
to sum that up, i need hardware specs. Outcomes of hardware specs i can calculate for, so i dont need to know those and neither does the person using it. With these i could easily find PSI and even recommend fuel octane.
