O.M.G. Wish I could by a set of four pistons, sleeves, rings, etc for $44 or $71 now. I priced the complete overhaul from Carter & Gruenwald about 8-9 yrs ago, S&P, all gaskets, main, rod, & cam bearings, but didnt get into things like a new oil pump, water pump and the total was over $2000. S&P were over $300 per hole.
MARLIN - What you say about today's batteries is true, today's better batteries are better than ANYTHING available even 10 yrs ago let alone 30-40-50 etc. But the "Good Stuff" only gets in 12V batteries. Several years ago I heard the automotive industry was going to develop a 42V electrical system, haven't heard abything about that for a couple years. More volts equals less amps so smaller wires, etc.
LUTHER - Any gas delivery truck I ever saw, from the IH tank truck Dad's gas man delivered to farms with, to the 18-wheelers Dad drove after he quit farming, to our LP gas man's truck all had/have pumps that you had to leave the engine running to unload. There were only a few fuel terminals Dad delivered to that had elec. pumps so he didn't have to mess with his PTO from the tractor to the trailer. His old White RoadBoss only had 400,000 miles on it when it was retired but had another 100,000 miles of pumping on the engine.
The engine problems you mention even effect newer engines. One spring about '94 or '95 My '87 F150 w/300-6 would barely start and run those first few days in the spring when the frost came out of the ground after work. The plug wires had been replaced once but the spark was leaking out around the plug boots and distributor terminals so bad it would only start on 3-4 cylinders. Another new set of plug wires cured the problem. I will say that after 300,000 miles & 15 yrs I've never had a problem like that with my PSD. The new coil on plug & distributor-less engine designs make that problem a thing of the past.... so far.
