Timing. C16 400shot making this as short as possible. 370 cubes. Fogger. 4150 intake. 400 ish shot 1550pph 40 jet. C16 fuel. My timing seems low. Running it at 7* plugs seem happy but traps the same as a 36, 330ish shot. Like I said. Plugs seem good as far as strap goes.
Are we looking at the plugs that were run with the 40 jets? What's the heat range? Are those R5671A-10's?
Are you adjusting your fuel with the fuel jets or a fuel pressure regulator?
We obviously can't see the fuel ring on the porcelain without cutting them open but your timing mark looks good. On the safe side, just before the bend, but that's where I like mine also.

plugs look like the right heat range sorta see the heat on the first thread only, I would add 2 degrees. For reference I've landed at 13 degrees with that big of a shot on a very similar engine and compression ratio.

Got to be careful with that. If you've got a cylinder out of wack, things can get hairy fast. That's why I wanted to see the other bank. When you did the initial plug reading, did they look uniform?

all the cylinders tested well as far as compression and leakdown. They all looked uniform and as always 3-4-5-6 were rich and all the outer 4 were lean 1-2-7-8. Timing on 6 and 2 looked the most "aggressive"
