WSM cast pistons - What are the limitations?
Hi, I'm currently doing some research for an OMC 56ci 70hp looper build this winter.
I figured to start a new thread, to keep the original one a bit more focussed on the general stuff.
At the moment I'm trying to decide on how far to take it compression wise.
In this motor I will use WSM cast pistons. I want to keep it reliable, while squeezing as much as possible out
of it.
My questions are:
-will the cast pistons survive with an SST60 spec head, using good fuel?
-will the be fine reving to 6700rpm, compared to the 6k stock?
Crank is forged, rods are no issue, from what I read. So I guess my week link is the pistons.
Thanks in advance!
