That front combination mounting plate/timing cover is unique. It looks like it's stamped Edmunds, and I believe that company went out of business in the 1950s so it would have been for an early Pontiac V8. I wonder if it's a piece designed for marine use.
This car reminds me of the Purple People Eater - I think it's owned by Alex Izardi and/or his brother Marky, they're in the Shifters car club in California (I also think Alex is a member here on the board who posts occasionally, hopefully he'll see this - he may know more about the car above.) Their car has a blown 316ci Pontiac that has been run at different times with fuel injection or
eight carbs.
