oversized rings and bearings

[devilsadvoc8]

So I found a rebuilt kits for my 420a. 336$. NEW PISTONS, gaskets,water pump, oil pump, bearings, and piston rings and timing belt. Good deal? They offer oversized rings by. 50mm and oversized bearings by either. 25mm or. 50mm. Should I get the oversized or not?

The size of the bearings depends upon whether the crank has been or needs to be machined. It's nearly impossible to tell either one until the crank is out. You also shouldn't get oversized rings, the entire piston should be oversized. But once again, that's only if the block needs to be bored which you won't know until it's measured and checked by a machinist. So I would hold off on purchasing anything until get the crank and blocked checked out.
