Hello Guys, just found out that Eagle has got a forged SBM crank with 4.250" stroke length:

Anybody did a stroker with this one and could supply the used parts / info about how much clearance work was necessary in a production block?

Running a 4" stroke at the moment, just thinking about future upgrades.
