Someone needs to start re-casting 340 blocks

It's all about volume. You can not compete with the volume of SBC and SBF users there are. Spend $300,000 to do a new 340 block and see how long it will take to

break even, if you ever do.

What would have worked 20-years ago doesn't work today.

Yes sir...and 300K would be a DEAL for all the tooling it would take, too.
