I would never go bigger than 4 3/8 and that is pushing it
Go back down to a 4.25 crank and a flat top piston. You'll have much better results over all.
No wonder it came apart.

If that is the crank that is in that engine it night be a good one, but hly hell that is a long stroke to be putting in that block.

Also a Bowtie talldeck is better then the dart or merlin blocks !
I just like them .

4.25 crank would have made it a 496+- depending on the overbore.
Anything bigger than that is worthless in that engine IMO.

Take the whole pile of iron to a machine shop down there. OWENS is probably the better one down there and let him TELL you what you have and make a decision on wether to mess with putting it back together based on real info and not speculation off of this board. He is up in Pearland. There isn't any other shops down there that I would trust with anything.
He will shoot you straight. If you need parts, I got a whole shop full of them. I got some engines down there right now also if yo uwant to look at some of them. He is running them on his dyno.
Find out what parts you have from him and I might take what is still good in on trade from you.

My engine is a standard deck Bowtie 454/509, with 4 " crank and 4.500 bore.
And still have room to go .90 over !!! easy.
U can easy build a 572 out of mine so a 620 out of a bowtie talldeck would be no problem.
The bowtie's are siamese bored blocks ,,i think the new ones are not ?!
The biggest crank i ever seen in a bowtie talldeck was 5.25 " stroke. Still running.
mmmmhhhhh.........................
I say fix the block and go with an engine builder that knows what he is doing.
