Thanks Everyone for you help so far
Here are the following things I will try based on your suggestions
1.. I will set the mixture screw on all 6 at 1.5 turn and adjust from there.
2.. I will exchange out 4.5 power valve to 3.5
3.. Different PCV valve.. perhaps current may not be the correct one.
4.. Advance timing to 25*
I wont be able to road test today as its raining heavy but will post with some photos today of the set up. I feel like I am close on this as it runs great with no bogging when I do WOT. Just issues of engine stall when choke is wide open at idle.
Do not set the outboards to 1.5 out!!!! The way to do it is set the center to 1 turn, ends to 1/4-1/2, and adjust your idle fuel bleeds until it idles. My carbs sat on a 312/590 cam and did not need no 1.5 turns. The center should be 1-2 turns out, and 1 screw bottomed should kill the engine, with ANY holley, if the bleeds are right.
