Carlo,I'm not sure you can install a full flow oil filter on you 230 ci 23 inch eng.,however, there seems to be a full flow for the Chrysler 25 inch eng. but may be difficult to locate a filter assembly. I have two glass packs on a '38 Dodge bus.cpe. which were run side by side all the way to the rear bumper. Sound is very quite considering the mufflers are glass pack.Your eng. is a very good looking job and the carbs.& hearders look great. Glad to have you on board at this site....... ... ....................Del, don't quit writing,we are mesmerized with your knowledge. It is very interesting and educating. We don't have many machinest walking around the shop that will share their experience. I wasn't aware the crankshaft in the eng.of a fluid drive had a drilling to allow the eng.oil to be transferred to the trans. Fluid drives were around in my youth but never tore one down or worked on any......Stay with us....Bo..
