Yes I am going to be sending all three parts to my local machine shop before I start my rebuild. As for the block as long as it is not cracked or compromised in anyway I will rebuild it even if it needs new sleeves. Also if heads are in good enough condition for a rebuild, I may still just go with some aftermarket aluminum heads, I will figure out the cost of rebuilding vs aluminum heads. If crank is no good what options do I have for a 340? Here's to hoping everything is decent enough to keep, and get f all of s good what con rods and type of balancer should I be looking for?
