I just got finished putting together a combo like this. I am running a .030 over 383 with the K1 6.760" 440 rods and using a factory forged 383 crank. I am using a custom Wiseco +18cc dome piston because I wanted higher compression and have Trick Flow heads, but I know Diamond has some part numbers for a 3.375" stroke and the 440 rod although from what I recall they may only offer .030" and .060 over" as shelf options.
Diamond will make them in the oversize needed , shouldn't cost much more than what they charge currently for the piston ... which isn't as cheap as it used to be ...
