Racecarl- Thanks for clearing up the pin thing, I thought that you'd still have some flow if the pin was not depressed/flush with the block surface.

Here's a picture of how I mounted and set up my oil filter using the following pieces:

On the block outlet (to inlet on filter) brass nipple, brass 45, compression fittings, 1/2" copper.

On the block inlet (return from filter at rear of block) brass street 90 (one side male, one female), original compression seat tapped for oil pressure line, 1/2 copper.

On the filter mount inlet-compression seat fitting.

On filter mount outles - brass nipple, brass 45 and compression seat fitting.

To mount the filter mount I made a j shaped bracket from a piece of plate steel that mounts to the top and lower front tapped holes in the block for side engine mounts. Then I used washers between that bracket and the filter mount to get the filter to clear the side of the block.
