R2 vs '62 Hawk 289

[Rick Allen]

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?,,,

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.

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!

 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.

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.?,,,

Yes..same block exactly...really the very best replacement engine block for your R2 build compared to the older partial flow Stude engine.

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.

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,,,

Well at least save the original block.

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.

Thank you, I will consider that when deciding what to do,,,
