why oldsmobile?

The issue with the Small Block Chevy was always one of metallurgy. The nickel content of the block was low compared to engines from Oldsmobile, Datsun/Nissan and AMC. High nickel blocks tend to last a lot longer due to reduced bore wear. Newer engines with EFI also have less fuel wash tendency that strips the oil from the cylinders and accelerates wear. These two reasons are why the Ford 5.0 is so well known for it's longevity. Many of them get taken apart at over 200k with the original cross hatching still visible in the bores and only need new rings. This is one of the reasons I chose the Nissan truck. A high nickel block, forged crank and rods, gerotor oil pump, timing chain with tensioner, solid lifter valvetrain, etc. all add to the overall reliability of the engine. Compare it to the S-10's Cavalier engine and there really is no comparison. The last S-10 I knew of from the late 90's which saw delivery duty was on it's 2nd engine and smoking-with only 180k on it. That and the 4 cyl S-10's had 4.10 gears vs the Nissan's 3.54.

The same is true of the LT1, while the several examples I know of were taken apart at about 150K, they still showed original cross hatching...
 
I can believe that. Most modern engines tend to last a long time if cared for. However, my point about the import engines is that the better companies have better electronics on all their engines (and cars in general) which adds to reliability. This is why they tend to last longer. Honestly, I dislike Honda engines, but they tend to have better electronics than GM. They also need more maintenance (timing belt, proprietary coolant and sealers), and love to pop head gaskets, which is why I stick to Nissan. GM makes good engines in their mid to upper priced offerings, but they have never cracked the small car equation. Their entry level cars have always been sub par compared to the Japanese. I don't want to sound like I only pick on American cars either, as the Europeans have their fair share of issues as well. Mercedes-Benz has lost most of their luster when it comes to reliability since the 1990's, and Volkswagen cars have become synonymous with stylish unreliability too. Let's not even start with British or French cars! I also have disdain for oddball Japanese brands like Mitsubishi or Isuzu as well. Nissan, Toyota and Honda make great transportation appliances in a way no one else seems to match. They are boring for the most part, but last a very long time.

For anyone who thinks that delivering pizza is not taxing like driving the same miles over a longer period of time, you just have to ride with me sometime. I bounce it off the rev limiter all night long, and corner on the door handles. I also have kept it repaired pretty well, but have also ran it out of coolant several times, did several 15k mile oil changes with the dipstick bone dry, and used to overheat it every day in traffic because of a clogged radiator. It has been pretty well abused. Despite all of this, and the jumping, mudding, drag racing,drifting, towing, etc. it has seen, it still runs like new. That is what impresses me. My 1995 Sentra (AKA the Shitbox) saw similar abuse before it died in a bad car accident that ruined my knee. That one used to get rally car driving practiced in it on dirt roads, and I let everyone who wanted to use it to learn handbrake turns and stunts. It ran so smooth that I used to grind the starter thinking it had stalled at stop lights despite having 143k on it when it was killed.
 
Well, i drive 2,000 miles a year on two vehicles. one is 25 years old now and the other is 31 years old. So much for somebody's THEORY.

Damn! I never thought someone could drive that little! I drove 20k miles a year when I was a store manager and didn't deliver. Even now, I work 2 miles from home and go to college 10 miles from home and still manage to do 8,000-10,000 miles a year that is not delivery. (I keep track of it all for tax purposes.)
 
The must of also cheaped on cams in the late 70's too. Better machining and FI definitly helped alot too. I worked with a Ford tech with 20 years experience and he noticied alot less engine jobs on vehicles with EFI. His words were the carbed engines tended to get washed down. The Ford had their Motorcraft junk carbs compared to the Qjet, which was alot better carb, along with most other Rochestor carbs for GM.
 
GM had quite a few issues with flat cams in the 70's-80's on the Chevy 305. I think they used a softer cam blank in the 305 than the 350 because the 350 didn't have that issue.
