1. Was wondering what the main differences between my M12 (late 90's Wheelhorse 312-8 application) and the other M series like M16 through M20, etc.?
2. Was told mine has (or had as I haven't checked yet and not original owner) a restrictor plate to choke it down a bit. Any idea what it'd be equal to if the plate was removed? i.e. would it be equal to a M14?
3. If I then run a jet from a M20, what could it bump up to?
4. Is there a point where they altered bore/stroke? How about the valve sizes?
IF they altered bore/stroke/valves at some point, my thinking is my M12 can hopefully be bumped up to the the power level of the last size it's identical to before or if they tweaked bore/stroke. i.e. if the engine is physically identical to a M16 then hopefully I could get similar hp/tq as that.
