340 Timing Question

With the good compression and the Edie heads, that setup shouldn't need much timing at all. If it where mine, 32 is where to start, and be safe. Should have a very torque happy motor and it ought to act like a big block, as you will probably find the flow limits of the heads, before it gets to crazy RPM. Most likely, an engine built similar, would finish off the door strike pin in my Duster.
Good Luck and have fun!
