I know my 65 273 Commando (Formula "S") came with the LONG filter... My 66 Hemi car and my 67 440 GTX also were LONG filters... And 69 340 Dart Swinger also...
I like the Mobil M1-301 filter (LONG) More filtration area... And more capacity keeps the oil level a little lower in the pan... thus helps with the crank not having to whip though it... (foaming)... Just my My thoughts... and 2 cents!!!
My 2009 6.1 SRT Challenger came with the SHORT filter with Metric thread... No way was I going to accept that!!! So, pulled out the metric nipple in the block where the oil filter screws in and put the old style 3/4 nipple (block is NOT threaded metric) and now use the Mobil M1-301 filter in that as well!!! Just Saying...
