If you use the ARP main bolts or studs you will have to have the main bearing saddles align honed because the ARP fasteners create more clamping force to reach "bolt stretch" or the proper "torque value" for that specific bolt/stud. This basically warps or distorts the main cap which requires them to be align honed to make them round again and bring them back into tolerance. For a street motor you could re-use the stock bolts if you're going to keep the power reasonable.....me, I use the studs and align hone, then you can do anything you want.
From the OP
" I'm thinking around 500HP would be a great weekend street/strip car."

By the time you find a decent OEM block and have it machined the way you want it, you could have bought a Dart SHP block or even a GMPP block. Both of which would give you more options down the road.
