Looked up my old machinest guy today. He informes me of a new design rod that takes the place of the old babbit rod and uses insert bearings. Also he tells me of aluminum pistons that can be installed along with a bore job that makes the old 216 into a 235. Some special head work to allow it to run on unleaded fuel and we are set. He also warned me of trying to drive the 216 engine a 70 mph, this is a no no. He said that the oil pressure is at best 20 psi. and had only dip oiling for the main bearings.
Hotrodders of that era preferred the splash engines because they were more reliable. Using aluminum pistons will allow a lot more engine rpm without hurting the babbett. I conversed with a fellow who owns a babbetted 39 sedan & regularly drives long distances on the interstate at 70+ simply because he replaced the stock pistons with aluminum. I don't recall if he had the Master or Master Deluxe. The Master Deluxe has a lower rear end ratio. If you put in aluminum pistons and inserts you will have NO problems. Just make sure the squirters are aligned. That's what keeps your rod bearings alive at speed.
