340 Block Bored to 4.160????? Help

Brand new unnused? Not likely. But posssible. People purchase stuff and never get to use it. At the cost of the DANM block, I'd be using it right quick for sure!

That's how I got my W-2 heads and intake... They were back up for a race team that never needed them... The boxes say "engine #4"...

Pure virgin parts that were never assembled in the original boxes...

Fortunately, they never blew up enough engines to get to need engine #4....
