  • Engine blocks ?

    Hi All,
    Just trying to fill in one of my many knowledge blanks. How many different V8 block castings were there?
    Thanks,
    Mr Mike

    Well, the quick answer is one. There is really only one basic Studebaker engine V8 engine block, not counting the one Packard block used in 1956 (it was a Packard), and not counting the GM McKinnon used in 1965-66 (it was a GM). However, in the V8 Studebaker block there are three variations, and when you add in the different cranks and heads, there are a lot of actual engines built on this block. The first generation V8 was the 232ci of 1951-1954. The second one was the enlarged bore with smaller lifters version used from 1955 to 1962 (224, 259, 289ci). This version used the same block, but it had smaller lifters and bigger bores, moved the fuel pump to the timing cover, different distributor, other variations. The last iteration of the same basic block was the "full flow" of 1963-1964, this was the same block as the other two, but it was drilled for oiling through an add-on oil filter in the lower right corner. This is the block that made the Avanti R1-R2-R3-R4. Many people prefer the full flow for the oiling improvement, but the earlier blocks are supposed to have tighter tolerances.

      Agree with ya whacker. I was told that the 224 had smaller valves than the 259 & 289. I looked in the book and the book shows the same part number for the valves used on all engines. Anybody know? Thanks.

        Jake; someone just got confused between the 232 and 224, No 224's do NOT have smaller valves, it is the same engine as a '55 259 with a short stroke! [^] The valves are all the same '55-'64 including Avanti, they just used the Stelite tipped ones, and of course R3 & 4 had bigger ones.

          Hmmmm..

          Not counting the "little" blocks, two...partial flow and full flow versions. I believe these were the only casting changes in the 259/289 series blocks.
          These may have also included interior (water jacket) changes between the partial and full flow around the cylinders since the right side of most full flow blocks have slightly different cylinder wall thickness's than the left side.

          Of course there may have been casting alterations to the few blocks that were used for the Indy engines, but of course....we wouldn't see those on the street!

            I think I agree with Mike here[:0]. I would've said partial flow and full flow. But beyond the accomodation of the full-flo oil filtration, the block's pretty much the same, back to the first ones made.

              And they change style of water plug in 1962. One was rusted out when I started up my Avanti 2 weeks ago after winter storage, and of course, the spare ones I had was the wrong style. I order the deeper style water plug and today I replace it. Tomorrow I will fill it up with water and anti freeze and burn some rubber.

                There were several casting changes.

                The 232 had a hole for the fuel pump push rod and other minor differences, the the later partial flow block, then the full flow.Oil return to the pan was also improved on the latest blocks because of the Avanti engines.

                  Hey!
                  What about the small displacement V8 block Studebaker cast up?

                        Man if you could only photoshop my Lark into doing the repairs themselves. Maybe moorph it into a 56 Golden Hawk while your at it.

                          Thanks for the info and comments guys!
                          I find it rather amazing that, in their first V8, they designed a block that would allow an increase in CID of almost one third with only a few minor changes! It would seem design prowess was not limited to Mr. Loewy.

                          Hindsight is 20/20 but I sometimes wonder what might have happened if the money Studebaker spent on diversification had been reinvested in the company?
