Help spec'ing out a new small block

We built our R3/W8 as the curtain was closing on most of this stuff. Actually ordered the block at work and was $2k…. That ship has sailed. Now you‘re faced with hunting one down and hoping you know what you’re looking at or is honestly presented as what it is. Then if you hurt it you’re stuck on the island of unavailability. Iirc we have 16k into the build…. and that was 2012. 2k block, 4K top end (W8 heads, jesel rockers, 598 intake), Molnar 4” crank, Molnar 6” rod, Crane cam (which slowed the build 4mos…. no cores at the time). Weber belt drive, Smith Engineering water pump spacers. Keep in mind I also had this mill built…. No hands on. While I did build my old big block, for the investment at hand I chose to have a pro take this on. While we have the parts with 1k hp potential, Brian at IMM chose a path for me that has resulted in a fairly quick, fun low maint combo. We’re only coming up on 300 passes after all these years. We really haven’t “raced” hard since 2016, and even then was only like 116 passes. Just an expensive hobby.
