The basic design of both camshaft quantities has got me thinking. Does the DOHC engine have the only advantage of being able to adjust the exhaust or intake timing independant to each other? Compared with the DOHC engine, if you rotate the SOHC cam any which way, then intake & exhaust are adjusted together. I suppose if the same engine (for example, the B18A Integra engine) was created equal, except one was a DOHC & the other was a SOHC, then output will be the same? Plus, you get less drivetrain weight & reciprocating mass thrown in as a bonus.
