We don't know the year or the series of engine so all we can do is guess the answer from our end.
That being said, if it is an "LA" block you will only get that big with a stroker crank and plan on spending a pile of cash.
If it is the 360 that I have read long ago that shared parts with the big blocks then you might be able to do that. I don't know. Best bet may be finding a used engine that just runs but spend some money if you want, we all have!
