Well thank goodness Christmas season is over. I can breathe again. I went out to spend some cleaning time with the truck today and got through a good 2" of gunk to reveal the engine stamp plate. Now I know it's a 305V6 but im curious as to if anyonr can decode it further, GM6066 guy didn't have any info on 305s that ended in a letter other then 'A'-'E'.

My stamp reads: 3050I907. The only letter being an 'i'.

Just curious on anyones speculation. Teardown begins tomorrow, with a build thread to start for those interested in following. Will add picture of engine stamp and atart build thread when back at a computer, on my phone now.
