223 length?

[ActionYobbo]

I am trying to find the length of the 223 engine. I have a flathead 6 in my truck and the 240/300 is too long so I was wondering if the 223/262 will fit. I need the measurements from the front of the block to the back of the block and how far is the head from the back of the block.
Thanks

From the tip of the crank pulley bolt to the back of the block is 31.5”

The water pump, pulley and fan add 2.5”

The head sits 1/2” ahead of the back of the block.

Hope this helps.
