361 stroker hybrid

[stumpyfine]

Hello all im Phil from New Zealand, this is my first post, I have a MS361 with 440 crank and 460 cylinder. Used a 440 carb,272 piston ,ms360 flywheel and modded 361 muffler ,all running good with original covers. Cylinder holes required a lot of slotting to fit the different bolt pattern and cases needed machining for crank clearance.

Welcome aboard! Would love to see some pictures and maybe hear more details about your build.

Not only that, but Adam is a known and reliable air filter inspector.

Run good?

Hard to believe that anyone could install a 460 top end on a 361 and get it to run. Truly an amazing feat in my book.

Not at all unbeilievable, just the amount of squeeze foe the juice.

How much difference is the bolt pattern.

& what exhaust is fixted to it..
“Edit” I reread your first post, , my memory must be suffering abit of Alzheimer’s

Any build pics?

The stroke difference is what counts more than anything. The 361 has a 34 mm stroke. The 460 has a 36 mm stroke. Therefore, a 460 top end will not work with a 361 crank.

p.s. Carbs are not the same either along with a multitude of other parts. Just MHO.

Depends on deck height of the case

He said it's got a 440 crank.

Has anyone in Michigan ever installed a Stihl 460 top end on a Stihl 361 along with a bunch of other parts that would be required and then created a stronger saw that ran well? Just curious.

I haven’t. But it’s probably been done before if it’s possible

Some pics not very good sorry, 3rd one shows how far cylinder hole is slotted. This was off a 440 460 hybrid so holes were already slotted. If using a new cylinder these could be drilled instead of slotted.

Sorry I missed the original tag.
Where do you stay Phil?
