Here you go:

Length-front of crank pulley to bellhousing face of block 37"
Width- outside generator on left to outside dizzy on right 19"
Height- bottom of pan to top of valve cover 27 1/2"
The carb and factory air cleaner adds about 6" in height.
The bellhousing face is just 1/2" behind the back of the head
The pulley and fan add 1" to length for a total of 38"
The engine compartment from the recess in the firewall to the radiator is 39" so GM allowed ONE INCH of total clearence.
My engines are both 1952 263ci and have all bearings, no babbit, and run 60#'s cold oil pressure and 45#'s at 190 degrees temp.
There is a 55 second series in the shop which came with a 235 and from the recess in the firewall to the radiator is 36"---3" short.
The 320ci Century/Roadmaster/Limited engine is even longer.
