  • 289 Engines and Cranks

    It is a rainy coldish day so I decided to spend time today in the workshop in the basement. I had several cranks which I had pulled out of engines several years back. I had two I had marked as 289 based upon the serial number on the engines I pulled them out of. I went out of my way at that time to only keep 289 cranks. I decided to clean them up a little and better store them. I was surprised on both of them that when I checked the casting number of 536452 to a cheat sheet from Ted Harbit, I found they are both 259 cranks. I do not think I kept the pistons so the question I have is can you put a 259 crank into what was a 289 and run it with the original 289 pistons? I would not do this but am curious. I am guessing the answer is no but I find it surprising to find this on two engines. I actually thought I had 5 used 289 cranks but I actually only have 3.

    I would not have kept them if I had known this. I kept one 259 used crank for some reason but always figured when you can buy a new one for 65 why use a used one.

    Thanks

    As you indicated the answer is no. Pin height is different.

      You can not use 289 pistons with a 259 crank. They probabaly would not reach anywhere near the top of the block to achieve approx. 8.5 Compression. The difference is the wrist pin location. The only reason that makes any sense that you may have had 259 cranks in 289 blocks, is that production type rebuilders in the day assembled them that way for cost and demand reasons (more 259's in use). You needed to check for one of (2) 289 casting #'s used. One # ends in 444. Tho I've never seen an engine that way, I've seen many with 289 cranks in 259 blocks. [:0][^]

          The answer is yes but might have trouble getting it to run very well as the compression would only be about 4.5 to 1 with the deck being about .300".

            Ted,

            Would something like this (low compression) run on the likes of pickle juice, apple cider or distilled cow pee? (Biggs - looking for cheap alternatives to gasoline [:I])

              You might be able to start it on gasoline and run it on kerosene like the old tractors back in the early part of the twentieth century.
              Only in most places , kerosene costs more than gas.

                Anybody else ever hear the story about the new '55 Commander that didn't have any power? Supposedly the dealership eventually found 259 pistons and a 224 crankshaft, or something like that. I think this was in TW 20-some years ago.

                  No didnt see that. But a friend of mine told me about some early 70's Chevy trucks that arrived at his Dads Chevy dealership. Seems they were 350 v8s with 307 cranks or something as they started real easy but had no power. They figured out these engines had a cr of less than 6:1 or so.
