Anyone have experience with the spin on oil filter adaptors for the early canister design blocks? What type did you use? Ive just learned a expensive lesson on how they can fail....

There’s an excellent illustrated explanation in the reference section that I followed with my 327 rebuild. Not sure that it applies to your 396.

I’m sure others will chip in.

My 65 327 came to me with an adapter already installed. Takes a PH8 (Ford) filter, works perfectly for 25 years.

I would recommend them, assuming they're the same as on a SBC. I put a spin on adapter on my '66 327 in the '80's that used a PH30 filter, just like the 350's used in the 70's. It worked fine. My brother had an adapter to an HP1 high performance filter in his '63 327. It worked fine too, but they were hard to find. Also, a quickie lube place put a PH30 in its place once. the HP1 used fine thread and the PH30 used a course thread. That was a mess to clean up. He swapped out to one with a PH30 adapter about 5 years ago to avoid having to find the HP1 filter.
I replaced mine after fighting with getting the old o-ring out too many times. My dad also had the oil changed by a professional once who didn't even remove the o-ring, just piled a second one on. Not surprisingly, that leaked bad.

I would use an Ice Pick to get the old gasket out. Worked great. I never minded the old cannister type.

Can you share what happened? I've always thought these adapters were ok.

Well here's what happened. I had a fresh rebuild on my numbers matching 396 in my 65 SS impala. We did all the required stuff for 1st run break in, pre lube with a pump adaptor, 40 psi oil pressure for about 10 minutes. Now we didn't have the valve covers off. I used the oil and additive the rebuilder required, original Quadrajet was also new just having a restoration by Sean Murphy [SMI] out of California. Dist is new also. Startup went well , nothing out of the norm to raise alarms. At this point the car was put aside for 2 1/2 years while I built another home and moved. So there was less than 2 miles on the engine. Car is back together, Woodward crooze week is here I get on the freeway with it, 10 miles or so it's getting hot and losing power, oil psi is still normal, it starts knocking! long story but it took out the main bearings.... On teardown the rebuilder said the "O" ring behind the adaptor blew out and was broke in pieces clogging the oil feed passage. 1st machine shop says 3 year warrenty is up sorry.....now in his defense we don't remember who installed that adaptor. Me or them, regardless I'm back for another 3K rebuild , crank is wiped out and were just gonna replace everything but at least we can save that block. This time I want the best design adaptor they make, that's why I asked for advice. So I have one other question,, is it possible that carb could have passed enough fuel dilute out the oil and cause this issue?? Fresh oil, maybe 15 miles on it and it was black coming out? :sad :

Oh wow, I'm sorry you had that happen. Expensive lesson.

I have never seen where that o'ring gave issues without there being an external leak. That just seems weird.

Update: I went to the machine shop the other day and they explained that the gasket behind that adaptor was partially stuck in the center oil feed passage because the adaptor mounting bolts were loose. This time we use Locktite on those bolts. Yes weird, just my luck...

I use the Napa 4061 adapter. I have it on a 327, 2 409s and 1 427.
