[Spridgets] Choices - heads, cranks, and blocks

[weslakemonza1330 at aol.com]

Turn them back upside and remove the sump.  If the 12CJ block is solid  
under the centre main it's arguably the strongest 1275 Spridget block.  The  
12CD will have a casting window under the centre main that you might want to  
tidy up and crack test.

They were sitting upside down and I didn't  notice the plate.  One is 
12CD/DA/H 25363 ('68 MK3 MG).  The other  is 12CJ/DA/H 36677 ('70-'71 MK 4 MG).
