I ended up getting two long block 6.5's with tin. Can anyone tell me what year and if they are oil spray blocks. I haven't taken them apart yet to see what went wrong with them, but was curious if the numbers are junk blocks anyway I probably won't mess with them. The first one has 12555506, F130, and then on the back of the block in the bell housing area it has F13 and then 506 below the F13. The other one is a 12555506, F148, and then F14 and 506 below the F14 in the bell housing area. Thanks for any info.
