But since it looks like you have pulled your old "500hp" hemi, just have it upgraded (rebuilt with more HP in mind).
That should save you lots of money using your block, heads, rockers, intake, etc.
iagree
On your deal I would use a 4.375 stroke crank with BB Chevy journals and 7.100 long BB Chevy type H beam or I beam roods with a good custom piston at what ever oversize you want to go to, I would make it the smallest bore that will straighten the cylinders up work
A 4.280 bore with a 4.375 stroke at 10.25 to 1 compression should make 1.20+ HP per C.I. on pump gas all day long with a decent camshaft, not a all out drag race cam twocents
I made a all iron stock street hemi casting pump gas street Hemi motor years ago with a Mopar 4.125 stoke with a 4.280 bore with less than 10.50 to 1 compression for a customer, it made over 650 HP with a set of stock 1967 carbs and intake boogie upscope
