CSX3305 Wonderful car, I think the 700HP is a bit optimistic!

When I purchased RS5024 in Northern CA in the early 1970's, this was the seller's "new" acquisition.
   
   It had just returned from Holman Moody with the SOHC engine. Very interesting car.
   
   Per wikipedia "With a single four-barrel carburetor they were rated at 616 horsepower (459 kW) at 7,000 rpm & 515 ft·lb (698 N·m) of torque @ 3,800 rpm". Two fours add about 50 HP.

Completely irrelevant comparison, one has a standard 427 OHV engine with twin superchargers while the other has one of the rare Ford factory SOHC engines.
   
   The twin blower machine is I believe one of two produced by Shelby.
   
   The SOHC engined car is a one off after market conversion done (I believe) in the early 1970's.
   
   The info I got from the owner seemed to indicate the engine replacement was very recent in 1973.

Certainly different but an interesting comparison in how to achieve big power outputs.

When i was growing up in Paris in the late 60's,  there was one there often parked  in front of a well known garage. It had a Cammer installed. I am trying to remember the name on the garage as they were well known in Racing at the time. The thing is, i understand Cammers likes to rev and combined with the car's light weight, it must be a blast to drive. The engine is a bit difficult to tune due to its rather long (6ft) cam distribution chain.

There was also a Cammer built at Brooklands in the late 80's for I believe a Dutch cusomer into an original 427 car not a MKIV but I don't remember the details........

The garage i think was Jean-Francois Piot. There is a resurgence for the cammer it seems, several manufacturers offer cammer engine builds, Dove is the most well known! At around $40K for a complete engine, it's not cheap!
