69 Mach 1 351c 2bl engine tag

[h20front 10]

I have been looking for the engine tag or stamp on the block of my 351 clev. So far ive had no luck. The car has an aftermarket intake which was there when I purchased it. So, no tag on top. Ive also crawled under the car looking on the drivers side back of the block from top to bottom. I dont know if its to dirty to see or its not there. My question is where exactly would I find the engine stamp on my 351 Cleveland:helpsmilie: ?
