Piston guided engine Gen3 hemi

Stewart Way · 10-28-2018, 09:09 PM

I have a thread on another forum about a modified Gen3 Hemi block that has been modified to use an LS main bearing setup to get a 360 degree thrust bearing. Problem with it is it is 2.93 stroke and due to the block being modified for the LS thrust bearing which is narrower than a Gen3 forged crank in order to get a longer stroke it has to be a billet crank. No forgings with enough meat to be cut for the LS bearing.
Someone responded on the other forum asking if I had thought about a piston guided setup. Either I don't really understand that setup or it won't help. Can anylone see how it would help and maybe explain what I am missing. As I see it the piston guided setup just floats the small end of the rod with tight side clearance at the piston and at the crank it really doesn't matter since the rod only has side to side of 2-3 thou. Still need to have the end play limited by the thrust baring. Don't think you would limit end play by using rod big end or would you?
Any thoughts. No not a SS build, just looking for better brains than mine.
