340 ta block whats it worth

its already 40 over??
yuck


What...!!
this is the thing that really gets me...bad info...There is NOTHING wrong with a 340 that has been bored .040/.060.
Where did this come from because I've sonic tested more good 340 blocks than I have 400's and I've never seen an ugly 340 thrust...now 400s that's something to make you cry.
There's no way that all the thick walled 340's in the world are in this town.I tested a min of 50-60 340 blocks and never come across something that even comes close to too thin to even think of using...
I wish some of the big blocks were half as good as any of the 340's I've sonic tested.
The 340 block that I have has a 4.100 bore with the thinest spot in any of the bores being .163.
This is an old wives tail...if I'm wrong please correct me.
Maybe someone who specializes in them might be of a different opionion...please chime in
Now 360's they are all over the place just like the big blocks but the venerable little 340 is a very stout piece.IMHO
