can any one tell me what year this 22r is ? the number stamped on the side is : 0407995 i'm looking to see if this is a feasable 22r/22re block. it's a 22r right now, wanting to see if i can make it a 22re . thanks

 

to make it fuek injected just get a efi intake and fuel pump and block off for the stock pump on the head and wire it and ecm it!! not hard but it should be fun

 

i got all that, just need to do it i guess...
