You first have to realize this project won't be cheap. That being said,really the only type of filter you can use without modifying the oiling system is a bypass filter, which seems almost pointless to me. However if you are going to have it apart anyway it is quite easy to convert to a full flow system.I am in the process of rebuilding a 216 as we speak. I am going to convert it to a full pressure/full flow set up. I had the crankshaft drilled for oiling to the rods by crower cams, (they seem to be the only ones that can do it, or at least want to do it, they have a cad/cnc program setup to eliminate missing the mark, once you see the crankshaft you will understand ) I also had them drill and tap the snout so I could bolt the harmonic balancer on, that just don't seem right to me,and it was only $180 for drilling the oil holes, the shipping was nearly as much though. That is definitely one drawback, but since the other engine has been running fine since 1979 I just amortized the cost over the NEXT 25 years, then it seemed reasonable (to me at least, but I am a bit nuts) You will definitely want to get the rods machined for insert bearings, You may want to consider drilling and tapping the 2 bottom holes in the timing gear cover so you don't have to take the entire engine apart to get in there, although there will probably be little reason to take it off, just saying...I will be posting my project on this website, for anyone to peruse. If you have any interest, just let me know.
