So with the help of an easy out, i got the oil filter adapter out of the 351 block, and screwed it into the 460 block. Then it was just a matter of installing the remote oil filter adapter. I went with one from Summit Racing, because you can rotate it to aim whichever direction you want. Made it a ton easier to figure out the routing.
Remote filter bracket on block. There are crimp-on AN hose fittings on it so i could see which way i wanted to angle it on the block.
Bracket for the oil filter housing
Where its located
Fits there nicely, with plenty of room to get to the filter. And its nice & stable too. I have my AN lines half-made- i put a 90º on one end so i could run them under the truck and measure for length. Now that i have that figured, all i have to do is crimp the other end on and theyre done. Then tomorrow morning ill just have to put em in, add oil, and (hopefully) start the truck!
Once i know it runs, ill continue working on the airbox.
