Oh man, how embarrasing. (Uncle Tony/Nick's Garage)

I ordered a set of small block lifters from advance auto or somewhere and when they arrived, the boxes were actually labeled as AMC lifters. 304 , 360 ,401 or something like that. I took one out and compared it to one that I pulled out of a low mile LA 360 , (I assumed they were original) and they were identical in height. I threw the set in and it never missed a beat.
