Wiseco/K1's new Coyote stroker assy and "caged" pistons.
SEMA 2012: Wiseco/K1 Show off Cage Pistons, 351 Coyote Stroker Kit | StangTV
My experience with Wiseco is that they will work with you, exchanging chamber molds for pistons domes, until they get it done to your satisfaction.
This new cage design looks incredible and hope they hold up to abuse over time. Not saying they would put a bad part out there but it's such a new design and ...man that piston looks light!
I just thought others might like to see this if they haven't already.
