a set of  white letters would make it  perfect in my book.  :))

i put lots of miles on an 81 4x4 long box that had the 305 replaced with 400 4 bolt main.

That was a great engine swap Harlan. 305ci small block was somewhat anemic in those days. IIRC, GM also offered their own Diesels in the C/K line at that time.

slip knot:
GM did run diesels in those years. IIRC the 5.7 oldsmobile motor was the 1/2 ton option and a 6.2 was the heavier truck option. Neither were very dependable. I remember when the 6.2 first hit the dealership I saw it had a Detroit Diesel sticker on the valve cover and I thought that GM may have had a good one. A few months later  we were pulling the heads and injector pump off for warranty work. All I really remember about that was it took an oddball headbolt, 18MM? I had to buy one off the snappy truck. :021:

oldcarguy:
I am glad someone agrees that swapping out the tired 6.2 liter diesel to a gas engine was a good move. GM's era of developing diesel engine in the vehicles was a farce. I owned two Oldsmobile fitted with the 350 diesel, one Chevy truck with 350, and two with the 6.2. They sure had their issues back then. But if you pushed GM they would stand behind them They did replace the fuel injector pumps with well over 100,000 miles many times. Unfortunately they didn't want it known they'd fix them out of warranted period. GM set the stage in the US for slow diesel sales. Plus the resale value was pitiful. I had to slip a 350 gas engine in the Oldsmobile to receive any offers.  The other determining factor, in my opinion, diesels don't like to be stored for any length of time. Then the issue of fuel sludge with lengthy storage. They perform best on long runs. Anyhow I had a 350 near ready to drop in  :)

Interesting take on what engine is better in the 80's. Actually I favor the 350 overall for dependability and power. For its' size it packs a lot of punch. In the big block category, the 454 is king. But in earlier years Chevy's small block 327 wins my favorite...

The bean counters ruined those early GM diesels. Once they corrected all the deficiencies of cheap head bolts, longer/stronger main bolts and upgraded the IP to a metal drive plate the Goodwrench engines were pretty decent diesel engines. But the damage was already done.

They did the same thing to the Northstar engines. After all the problems were addressed with regard to the head bolts, water pump, and engine sealing in the 2005-2006 model year, the Northstar was actually a wonderful V8. --- BUT it was too late, and the damage to the engine's reputation was it's downfall. They killed it in 2011.
