Default question to experienced engine modders

heres my question to some experienced engine modders out there,what will happen to an engine if you install a modified crankshaft into an engine without porting and polishing the sleeve?example: powerhouse mods modified crankshaft into a nova n21b stock sleeve,will it blow the piston head into pieces or it will not start or run properly?im just too being curious thats why i asked.
heaven smiles above me

If it has a wider timing it will run more powerfull and probebly more agrassive on the throttle.

You will not blow out other parts but the more power and acceleration does give extra forces on the piston and conrod and could wear out or break faster so a better rod like the R7 is adviseable.
The quality of an answer comes with the quality of the question.
