Rick Allen Posted January 21, 2023 Report Share Posted January 21, 2023 I need to replace my '63 R2 block and have a '61 289 block from a Hawk, can anyone tell me if there are any differences between the 2 blocks and if so, what are they?,,, Link to comment Share on other sites More sharing options...
64studeavanti Posted January 21, 2023 Report Share Posted January 21, 2023 The 61 block will be partial flow oil filtering and your block is full flow. What is wrong with your block? Many issues can be repaired. Link to comment Share on other sites More sharing options...
Rick Allen Posted January 21, 2023 Author Report Share Posted January 21, 2023 Block is cracked, starts below the freeze plug but doesn't start at the freeze plug, I don't have much faith in repairs like this holing up or failing at another area again! That being said, is the oil flow the only difference in the 2 blocks and can the '61 block be converted in some way to be full flow,,,thanks for your reply!

mfg Posted January 21, 2023 Report Share Posted January 21, 2023 My opinion.....Late '62 - '64 Studebaker 259 and 289 full flow blocks are still relatively easy to find...purchase one of those as a starting point for your build. . Link to comment Share on other sites More sharing options...
Rick Allen Posted January 22, 2023 Author Report Share Posted January 22, 2023 Thanks for your suggestion; I know of a '63/289 4bbl that's available, so that would be the same engine block as my '63 R2 and I wouldn't be sacrificing anything, nickel content the same in the R2 as in other late 289s, etc.?,,, Link to comment Share on other sites More sharing options...

Nelson Posted January 22, 2023 Report Share Posted January 22, 2023 Yes, late 259 pr 289 full flow block. But if your Hawk is a matching number R2 id look for a reputable shop that does this kind of work and have it repaired. Link to comment Share on other sites More sharing options...
Rick Allen Posted January 22, 2023 Author Report Share Posted January 22, 2023 Thank you for your suggestion, I agree about the matching #s but I worry about that type of repair, I plan a complete rebuild and don't want another failure/crack after going through all that work and expense,,, Link to comment Share on other sites More sharing options...
Nelson Posted January 22, 2023 Report Share Posted January 22, 2023 Well at least save the original block. Link to comment Share on other sites More sharing options...

If the full flow engine you've found does not work out, I have an extra 'bare' 289 full flow block which has been cleaned and inspected I'd sell for a reasonable price.
