I bought a used SOHC 427 in 1996. Had planned to install it in a 1968 Mustang, but the project never happened. The engine hung on an engine stand for 4 years until I sold it.
One day I was staring at the SOHC motor while it was next to my Cobra, which had a 427 medium riser. I remember wondering how much wider it was than the wedge motor in the Cobra. Grabbed a tape measure.......8" wider. And HEAVY. There was a lot more cast iron weight in those heads. I stacked 4x4 wood blocks between the
oil pan and the bottom frame of the engine stand to help support the engine. Without the 4x4's the engine's weight was slightly bending the upright portion of the stand.
Several times while looking back and forth at the wedge and cammer, I had no desire to put the cammer in the Cobra.
