Need some help. I pulled a 383 motor out of my 69 runner. No it is not numbers matching. Looking for another block that is stock not bored out yet. When reading the number's stamped near the distributor. Would it have the HP stamped on it. See the E 9 68. Know it is a B block. In the casting number would it have the B or the RB. Had all this wrote down some where but cant find it. Thanks for the help. blue69runner.
