I had one of them in my garage from 1996 to 2000. I finally realized it had to go to another owner, as I was space and money challenged to start another car project. We already had a 1966 GT Mustang and the Cobra. I sold the cammer 4 years after I purchased it for exactly what I paid for it.
It was a looker because of it's size, the 2x4's and the rarity factor, but geesh it was it big and heavy.
Everything was iron except the intake. The day I purchased it and placed it in the bed of my then 1988 Nissan pickup, I knew it was a behemoth. The Nissan's nose started facing upward because of the weight. When I arrived home and hung it on my engine stand, the stand's vertical post began to lean forward and downward slightly.
I had to insert blocks between the
oil pan and base rails of the engine stand to help support the weight. My other 427 wedge motor never caused the stand to bend.
Once, I measured the width of the SOHC and compared it to the wedge 427. The SOHC was 8" wider at the valve covers.
I enjoy driving our Cobra through curves, and do a little road racing. My wedge 427 has aluminum heads and intake, but is still heavy enough that it induces some understeer. Some day I hope to build an aluminum block 427 to further reduce the weight.
The weight and size of the iron block/iron head SOHC places it last on my list as an engine for our Cobra. In general, the size of the SOHC stuffed in a Cobra engine bay is very space-robbing for me. If I had kept the cammer, I'd have put it in a car intended for straight-line use; Mustang, Fairlane or Galaxie.
