I just modified my '57 235 block to accommodate a full flow filter and searched the 'Bolt for mounting ideas and adapter kits. The topic has been covered pretty well, as 49 geezer mentions.
Here's a link to a good thread that contains a link (provided by 49 geezer)to NAPA for the kit.
I still haven't decided where to mount the filter, but like the pricing of the aforementioned kit. Also, if you scroll up in the thread you'll see a photo of a manifold mounted filter.
One 'Bolter, I forgot who, stated something to the effect "to heck with all of this filter nonsense as the old engines are still clunking and will continue to do so after we are gone."
I've given careful consideration to that advice and tend to agree to some extent, but nevertheless did drill and tap the block for the modification. I just wish my engine wasn't torn apart right now allowing me to do so.
