The oiling system I use and install on cars that come through my shop is similar. I use a rear adapter, a three port filter adapter that is bolted to two tabs that are welded to the left side motor mount, this locates the filter in the perfect location. i use a fluidyne cooler and lightweight lines and fittings. This is very similar to the systems you are talking about. It would cost about $725.00 for the whole system, if you have the rear adapter you can deduct about $100.00.
It is very effective.
