How to build a 13 second 340 Duster

Hey Idaho, you're getting some damn good advice here, these guys are good. One thing more that may have been covered but I missed it, is the 340 you're going to use should be completely disassembled and inspected up the ying yang before you decide it's ultimate fate. Judging by you're threads you can easily do the tear down and cleaning yourself but then a good shop will be needed for the crack inspections of the block and rotating assembly. Just my 2 cents.
