Horsepower for a 72 with a 400 - The 1947 - Present Chevrolet & GMC Truck Message Board Network

My friend has a 72 Cheyenne that says 400 on the front side. I am a little confused as to wether this is actually a 402 Big Block or 396 small block. It seems pretty quick, especially in the mid-range. Feels like 0-60 is in about 8-9 second area. I have searched previous posts about this. Do you think a stock 400 would be that quick? Seems like estimates are from 210-375HP and from 300 to 400 lbs/ft so I really I have no idea which one it is.
