Hi, I am not sure which nailhead my car has. My grandfather started out with two cars and I don't know which engine went where. The stamped number off of the block from near the distributor (which is in the rear) is 11-5752. And the stnped number from the intake manifold is 1163200-3. I don't know how to read these. The numbers off of the tag under the hood is 1954 MOD 54-48D Style No 54-4411D Like I said, I don't know if it is the original engine. Point me in any direction to figure out the stamped numbers meaning. Thanks, Jason
