Ive ran Fram for 12 years now and just last year switched over to mobile 1 filters.
or some kind of burp arrestor, back fire that isI am curious as to what that thing is that sits inside of the filter element that is permanantly fixed in there.
I am guessing that it is an intake muffler so that you cannot hear the secondaries trying to suck in the whole states worth of air when you get on the skinny pedal hard.

That was my guess. Marine motors are required to have a flame arrestor of sorts.

I just talked to my engine builder a day or so ago about what filter and oil to run in my new engine. He said fram was junk and recommended ac delco pf35. I haven't looked for one yet. I was using fram. I think I want to see the inside of the filters now. He said he has cut a number of them open. Has anyone checked out the K&N oil filters? their price is sure high.
My engine guy also recommended straight 30 weight oil for southern California's climate, for my engine (built 402-430 cu. small block for high torque and 5500 rpm max. -waiting to see if we are going with a stroker crank or standard 400).
What brand and weight oil do yo guys prefer? Hope I'm not going too far off topic here.
I think I will save the last one or two fram filters I have for my wore out blazer engine, or cut one open to see the proof.

You know, thats actually a little scary. If I remember right, the oil comes straight out of the pump into the filter.i've been running k&n oil filters for 2+yrs now. i used to use fram's toughgard & other brands also. BEFORE i swapped to k&n brand of filters, with a fresh oil change & new filter, my pressure gauge would stay constant @ 40psi & over time it would gradually go down, finally reaching @ 30psi when it needed the oil changed again. it did this every time regardless of brands.
the one exception i've found is with the k&n filter, my gauge now reads right at 60psi on fresh oil & a k&n filter change, slowly falling off over time to @ 50psi when its time to change the oil again. i first tried the k&n filter just to try one, but to me the increase in oil pressure justifys the k&n's price
they had it on TNT last night.... 
Damn, maybe I better change it.......They had to sign all kinds of top secret papers before we could let them model him after me.not to drag this off topic, well ok, yeah, i am, but every time I see you post now with the new sig Fordum, i think of the movie "Men in Black"they had it on TNT last night....
