oops right! block # is k3769716 ser # next to dist. is T- 666899 which matches the # on the I.D. plate inside the truck and the head is an 848 head .
there are no bars on the opposite side of the block. I have a 261 engine here and the bars on it look nothing like what I have on my existing engine.
I tried to post a picture , hope it comes through.
