Value of a 340

Seems like if you have a core 340 or 360, $4000 would go a good way toward building power. I think you can build basically stock (machine work and a good kit) under $1500 anyday. As far as cores i got one complete on ebay last year for $326 if i remember correctly (which is obviously cheap). There has been a local ad for a $600 short block 340. If you arent set on a 340 a 360 is cheaper to buy, easier to find, and a little cheaper to build (not to mention more cubic inches) I think about a week ago or so there was a 340 on ebay in charlotte for 2k. It had been pulled running i think to go bigger
