Offshoreonly.com - Race Engine rebuild

after much consideration, we have torn down the engine locally and decided to rebuild it with a standard carb/manifold set up.

Upon further inspection of the components once the engine was opened, here is what we found:

the block is a 454 gen IV bowtie tall deck, with 4.500 bore.
heads are GM high perf 118cc
flat top pistons

the crank is a crower with the following specs (which I hope someone here can help me identify)

and these engravings, which i wrote down, as well

given that its a tall block and a bowtie, which is already 4.500 bore, I would like to install a 4.500 crank and 6.535 rods , which would make it a 572cid.

What are you guys thoughts on this? has anyone built up this set up before?

Will i have to grind some clearance in the block for the 4.500 crank?

Thanks guys.
