331 Stroker Rebuild

So, ive got moderate mechanical ability and i was told my recently built 306 might need another rebuild due to a spun bearing.
I think i am going to tackle a rebuild myself if thats the case.

My main question is, being that my block is currently bored .30 over and i would like to keep it that way... would i be able to keep my pistons and use the 331 stroker kit's rods, crank, etc? or do i have to get another block? and if i were to be able to use my 306 block, would a 331 turn into a 335?? or would a 347 be a 351?

also where can i get the correct pistons for a 306? im not too savvy on the mesurements and ters when it comes to aftermarket internals

and if anyone knows.... what kind of numbers can i be expecting with a 331 and the mods listed in my signature.

THANKS

You can not use your pistons furthermore I would suggest if you do not have the necessary tools to accurately measure the dozen critical clearances that need to be checked when building an engine, you steer clear of doing it yourself. You more than likely will end up in the same situation you are in now. Also if it spun a bearing did the bearing spin inside of the main bore? If so the block needs to be align bored again.
