Cool this is why I like to just go straight to the Aluminum case. Already shuffle pinned drilled for full flow and opened up for whatever cylinder you want to put in there. I don't usually go over 90.5 or 92 thick wall. also clearanced for stroker. then I put a 78 in there. still bulletproof. IMO. Better more stable material (aluminum less expansion and contraction) My buddy got over 150k miles on a aluminum case engine.
It keeps the 2 halves of the case from "shuffling" or sliding back and forth against each other in higher performance applications. We like to do them when you get into cranks bigger than 74mm.

Very good video. Thanks.
All in all the sense of shuffle pins is discussed controversially.
Would like to see video on the case welding improvement, have you done that video yet?
Very nice. Thanks for posting.
nice, keep 'em coming!
Awesome work ! What do you charge to shuffle pin?
We charge $75 to do the center mains or $140 to do all 6. I'll put a link in the description to the product page on our website.
Show !
So,essentially shuffle pinning is adding a hollow dowel at the case studs? Kinda like locator pins the studs go through?
Yes, that is exactly right.
shuffle pins are too loose imho, should be a slightly snug fit
They need to be quite tight when cold to compensate for thermal expansion of the case when hot.
i was hoping to see the full buid in video's , what happend?
We are so busy in the shop that we have not had time to make videos. We still hope to get back to it, but our backlog is crazy long right now.
What is the purpose of the shuffle pins?
