305 rebuild question

What are my options here, will the block handle boring out for 351 or 401 slugs?

If you're looking for more cubic inches then you will be better off locating a 351 or 401 engine Both engine blocks are cast with considerably larger bores, you could possibly try boring the 305 to the 351's bore but there will be nothing left for cylinder wall thickness.

Thanks for the feedback, thought it was a stretch, but had to ask, trying to find a larger displacement engine is diffficult:signthankspin:
