RE: Ls or ss?
Are you asking what the differences are between the SS and LS engines? just curious or what? any time you want to know specifics about a Nelson engine, you can email Dave Shadel at Performance Specalties.
The long stroke has:
smaller bore, this smaller diameter piston
longer stroke ( big guess, but I think the stoke is .790 )
taller case to accomodate longer stroke (I think the case is .080 taller?)
new carb
new back plate
new head design (both inside cut, and head fins)
Hope that helps. ??

post a pic of your engine. The SS engine is easy to install a plug with your fingers(short head fins) the LS has "taller head fins" and can be a bit of a challenge to install the plug with your fingers and the back plate only mounts/installs in one position,,, get it wrong and you'll ruin the engine when you hit it with the starter

That's true DN... the best way to tell is pull the back plate and look for the 2 notches that allow the piston to clear. The short stroke didn't have that.
