Okay, I'm a machinist on the side, as a part time business. My garage is a regular machine shop. When I buy a used vehicle, I always tear it completely apart and see what makes it work, and always look for places improvement is possible. (Somebody already beat me to fixing the STC fitting, but that's an example of what we're looking for.)
I haven't been into the heads yet, but if I'm correct those standpipes appear to be plastic? (Modifying the entire upper HPO system is a thought. Unless people consider it reliable enough, it wouldn't warrant brass or stainless stand pipes?)
I'm also making an easy to install oil pressure manifold that screws into the location for the factory oil pressure switch. It will have 2 fittings at 1/4 pipe thread, and one at 7/16 x 20 for the factory switch.
Looking for idea's......equipment standing by.
