with out being able to run the vin# you'll need to look at the block. like i said, pass side on the block under the head, it will say 400 or 455 or what ever it is, and under it or next to it is a 2 or 3 letter code. ie: 400 YS....the code tells you what hp the engine was rated for and other engine specifics.
