Stock 340 Rebuild
I just reused the 0.040 over Silvolites because this is supposed to be a low buck stock build (hahaha). Mill the heads and replace the valves with nail head valves and I should get around 10:1. I saved on pistons and rebalancing... got to draw the line somewhere. I still spent $2k at the machine ship with cleaning, honing, cam bearings, rings, bearings, crank grind and rod resize. If you are going a little deeper I would do the KB243 pistons (as mentioned) and rebalance (and get aluminum heads) ..... there I just spent $4k more for you. :)
