I have two block sitting here. One says 4G63 as a casting. the other says 4G69. The are IDENTICAL everywhere I can look. I can't find any difference except the numbers. Can someone help? I am almost positive that the 4G63 is because it is a 03 block year and the 4G69 is a 05 year??

 

the 4g63 is out of a evo or a dsm the other block is way dif

 

from what ive gotten online. its a 2.4L Mivec engine. I take it I can't use it in anyway??
