What the correct weight and how many quart is these 5.0 take. I have few fox 5.0 in the past, but I cant never get the dip stick to read right, some take 5 quart, some take 5.5 quart to get to the full dot mark.

I alway use 10w30 and FL1A oil filter, I might be wrong, but did some one mention 10w40 is better for these 5.0 ?

I always use the motorcraft filter. It's oe spec and readily available anywhere.
You need to mark your dipstick. They are horribly inaccurate. Full with 5 quarts and then make a mark on the dipstick. Now you will always know what the correct level is.
 
I've been using FL1A filters for eons, with that being said I have just recently switched to Wix. If you cut the filters apart and compare them side by side the Wix line uses an actual spring to hold the oil bypass closed where the Ford filter uses a bent piece of metal. The bypass will fail open much sooner on a Ford filter than a Wix. Fram has to be the worst option since they use no spring at all and simply have cardboard holding the filter together.
As far as oil goes, I prefer Brad Penn "Green" oil. It's a partial synthetic and has high concentrations of Zinc that helps prevent scuffing and extends bearing life. I run 20w50 in my race motor and would recommend staying with the 10w30 for a stock fox motor.

Motorcraft FLA1 and Conventional 10w30 Castrol is what I've always run. John Force uses it in his Mustang so its gotta be good enough for me!

Thats what I run as well.

FL1A is rumored to be a Purolator PureONE filter in a conventional case...so I sometimes get those if they are on sale or part of the oil change deals when AZ bundles it with the 5 qt jug
 
ford filter fit in quiet few different make too, I use FL1A on my jeep 4.0 :rlaugh:
I agree with what you're saying, I do hate to tell you that John force definitely doesn't use a Ford filter...
