Sure, you can get away with using plasti-gauge, I've built plenty of american motors with the stuff, but with the tolerances in these bearings/engines, I probably wouldn't go that route. If these guys are using plasti-gauge and going that route, that's a non-starter for me.

You can't get a bore gauge inside the S65 to measure the rod big-end. Plastigage is your only choice to "approximate" clearance with the engine inside the car.

So, if your crank is within the tolerances of what BE expects it to be, then the bearings should create the intended gap that BE was aiming for.
I don't know if it's a fact, but I've heard that some shops don't measure the crank rod journals, but give the journals a visual inspection and then proceed.

It is a fact, plenty of photos posted to show it. Bert will be at my house this weekend measuring bearings.
