I go to the Chevy truck section almost daily to answer someone's question on the net.
I did find this on the Gregwapling site
2135412 GMC 46-54 200, 270 =3D 4
2193980 GMC 52-54 302
2324002 GMC 55-62 248, 302
2324003 GMC 55-63 270
2324004 GMC 55-62 302
2404929 GMC 55-63 270 =3D 4m

Then more searching finds this from the OLD GMC site that I have looked on a number of times and hadn't seen. Hope it's on the bottom here is the link to go with the image. http://www.oldgmctrucks.com/Photos/GMC_Numbers.htm
The casting number will be on the side of the block (I'm not sure exactly were) and between it and the stamped serial number you can get about as close as you can.
