    4 mil stroker crank help?

    Ok so on my 86 trx I'm running short rod stock cylinder bored to 67.50 ported cylinder is decked and cool head. My question is what is the 4 mill stroker? My quad is healthy now so do I buy a 4 mil rod and put it on my crank or a 4 mil complete crank? What all would need done? Spacer plate underneath is all? Different porting? What would I notice with my setup now but with a stroker crank? Snap or what would improve. Any help would be appreciated

    cylinder needsported for a stroker crank.you can have a co build it or buy hotrod crank.yes you willneed a spacerplate.yes you will be able to tell the difference.but if your crank is good would i go that route?no not really.due to needing case,clearanced,cylinder ported,and all the extra work.
