I'm waiting in the belt drive. Using old timing chain setup for mock up purposes. I new going in this was going to be an issue. It's not my first go round with long stroke stuff. I just want to cover all my bases cause I'd rather not have a situation where the motor clearances itself. The cam is degreed where it needs to be I will clearance the rods so it will spin. Then I will back it up 6-7 degrees spin it if all is good I will advance it 6-7 degrees and check clearance. It was recommended by the rod manufacturer to use a long zip tie to measure cam/Rod clearance... Feeler gauge is a no go.

Where it gets very interesting with a standard cam core and roller springs is how much the front of the cam turns before the back. When you put any kind of spring pressure on a standard cam it twists it up like a pretzel.

Have you checked it yet? The XD rod will sometimes clear a 55mm with a 4.75". If it hits, the clearancing will be very minor. Here is the interference on an Oliver rod, which has a bigger shoulder then the Callies. [ATTACH=CONFIG]539260[/ATTACH][ATTACH=CONFIG]539261[/ATTACH][ATTACH=CONFIG]539262[/ATTACH]
