Guys,

I recently just changed my camshaft to evo 8 ones. Upon removal of my engine cam cover, i notice that the camshaft in my engine have been changed before (btw i purchased a preown Airtrek T). Written with pink marker pen onto the (102130322) intake camshaft was G746 and at the (10213000) exhaust camshaft was G753. Any idea what these letterings means & which evo engine family does these camshaft belongs to??

Confused...
