Want to put a magnum 5.9 in my 70 dart.
I did a 70 with a later spoolmount k member and a 727.
I added an electric fuel pump and had to grind some ribs off the block to make the la headers fit.
I used a 90 degree oil filter adapter and knocked the locating tab off of it so I could turn it for best clearance.
Slot one hole in the magnum flexplate to match the LA converter.
