340 damage dilemma

Krooser said

The shop that has my 388 (383, 386, 409 depending upon your calculator) has a new Rottler F88(?). If they run it at speed (they don't) they can bore the block, install one sleeve and deck both sides in less than an hour so I'm told.

They don't like using up the cutting tools...and they seem to wear out those tools faster in a Mopar block...

Depends on the tooling. If they are using carbide, they should be able to run it wide open and get "good" tool life.

No matter what they do, a Chrysler block and any aftermarket block will always be harder on tooling than anything else.

How do you think GM made their junk so cheap? Ultra soft blocks and heads so you can just smash the tooling through the material and things like open bolt holes (rather than blind like they should be) to make the junk as fast and cheap as they could.

And then there are things like compacted graphite cast iron.

That stuff is stupid hard and is hell on tooling. Great for power though.
