A 360...Commando?
Do you possibly mean Magnum?
If it is a Magnum block, I don't believe the early 90* adapters will seal due to different machining in the filter boss.
Engine was bought in 93 from year one, have the paper work when purchased. Now I can only guess it’s a LA engine cus it the spec sheet didn’t come with and did find searching the web everything points to a 360/360 and purchase paperwork shows that.
