hello royleeair. if you can, jump up and look straight down between the fire wall and the engine. on the drivers side and on top of the bell housing flange there will be a number cast into the iron[seven or eight numbers]. you will probably have to clean this area to see the number.it is a block casting number and will further identify the engine. then either tell us the number on this forum and those of us that have a list handy can tell you what it is, or you can look it up yourself as was mentioned earlier on the mortec list. good luck.
