After quite a bit of sketchiness, I received a block from Muscle Motors about 18 months ago. Took the block to Best Machine for machine work, and eventually had them build my 498" B-engine (4.500"×3.915"). Way more machine work than should have been required on a new block, but it is done. Just packaged up my headers to send to Jet Hot, and finalizing the dry sump system. We will find out soon if it makes the 1000+ hp NA on gas. I'm counting on it holding up...can't afford for it not to! Stay tuned on my Bonneville Speed Week 2019 thread here.
