I'll tell you the whole story. I bought a 1964 Falcon Sprint about 5 years ago. I started to do some research about the history of these cars in general and found that in 1963 and 1964 Ford aggressively sponsored these cars as rallye race cars in Europe. They then were nicknamed the Monte Carlo Falcons due to their successes in the Monte Carlo rallye in Eurpoe. When the Mustang came on the scene in 1964 1/2 or 5 the Falcon was no longer the premier rallye car. It was replaced by the Mustang. The Falcons then were used in road racing and saloon racing and may have continued to receive some factory support. Mind you there were only 15 of these cars produced in 1964. They received preliminary work at Holman & Moody and then were shipped to London England where they received additional preparation for the rallye racing. There are 3 of these cars known to still exist. So, I thought it would be a neat idea to make a clone of the original Monte Carlo car and road race it in a historic class that does not require a documented race history. I then acquired the homologation papers that provide some specifications. During preliminary reading about the cars it appeared that they had a K-code or Hi-Po 289, probably the same as a k-code Fairlane. Then when you read the homologation papers you learn that the specs do not match a regular k-code engine. The valves are too big, the chambers too small and the connecting rods way too heavy. My thinking was that Ford (Holman & Moody) may have used the Lemans or GT-40 type heads and rods in these engines. The homologation papers list the heads as cast iron. The specs certainly would indicate that is the case. The cam listed has a Ford part number, but as of yet I have not been able to identify what it came out of (C2OZ-6250-A). Any ideas?
