It’s Winter. Let’s discuss strokers. How much faster

I think one way to "justify" it is this....

A head change is easy, cam change not too bad, rotating assembly, ugh...

So, with that in mind, one might look at this as a long term project. Stroking the motor shouldn't have any adverse effects, so doing that first and bringing everything else in line over time might be a good way to spread the pain out out over time and see an immediate return on investment.

Just thinking out loud.
