engine block

Hey! someone who can determine the image if it does something that looks like this ? Nothing stands out but looks generally bad cut out ? should you grind it and make it finer or I can run like this?
Do not know how it looked like before but the main bearing broke and now I have bought a complete new crankshaft me to tuck in .

Is there any evidence of welding if you flip that case half over? Really just looks like somebody roughed up the bottom case to help with air/fuel mixing, like is done sometimes on the intake runners. Haven't seen that before but I wouldn't worry about running it.

It fine to run.

Looks trenched for added stroke.

no, there are no repairs / welds on the block . it is a 5mm stroker crankshaft sitting in

Case was trenched for clearance for the extra stroke.
