Very interesting thread!
All of a sudden my 527 Shelby "big Bore" engine looks like a small block 
I will follow this thread carefully

#5 and #6

Here is the pics of the plugs. The plugs look pretty consistent to me with #4 and #8 slightly moist
#1 and #2 first

Yeah, something is going on. It fell flat on its face at exactly 5500rpm. The HP curve was still increasing when that happen and from earlier dyno sessions I know this engine will easily do 6000.

The #4 actually has a slight mist of oil on it from what I can tell , it is not matte black like pure soot but ever so slightly "moist".
I'll roll up my sleeves, bust my knuckles, and yank the other 7 plugs out and have a look . I'll post pics for you to see.

What also worries me is what Nightmist66 said, vacuum or exhaust leak. I can't find any evidence of an exhaust leak from the heads and the O2 sensors are in the collectors before the joint. There is only one vacuum line, going from the throttle body to the MAP sensor, and it looks good. Line is new, fittings are new.

Thanks for the comments.
I yanked out #4 since that is the easiest to get to. Looks rich to me...

Thanks for your feedback guys.

Here is what tech support at Moroso answered: "Our stated capacities are always just the pan. So it would be 8, plus the filter."

So I guess 1qt in the filter before it goes on + 8qt in the pan, start it up, let it sit off for a good while and then pull the dipstick and make a mark will be fine then

Hopefully their tech's answer confirms what is in the catalog. I hate when you ask several people and get several answers. I would say if they tell you different, I would start at 7 quarts in the pan plus filter and go from there. Easier to add more than take away.

Yeah, lets hope he does

Who makes the pan?  I thought Canton's 8 quart pans were total "system" capacity including filter.  An email to whoever made it would give you their opinion

Pan is from Moroso. I'll shoot them an email and ask
