you would have to have an original work order from the dealership listing the package was installed on the car. the car would also come from the Pontiac plant. the emblems for '64 n '65 were placed on the pillar unless the car had a vinyl top. my "64 RB had one emblem on the rear decklid on the drivers side opposite of the gto emblem because it had a black vinyl top.I am going to look at a GTO next week and it has a sticker on the car that says Royal Bobcat.How would I know if this car had the Royal Bobcat package?
The kit will include the following;I am going to look at a GTO next week and it has a sticker on the car that says Royal Bobcat.How would I know if this car had the Royal Bobcat package?
Throughout the 1960s, Ace Wilson's Royal Pontiac, a Pontiac car dealer in Royal Oak, Michigan, offered a special tune-up package for Pontiac 389 engines. Many were fitted to GTOs, and the components and instructions could be purchased by mail as well as installed by the dealer. The name "Bobcat" came from the improvised badges created for the modified cars, combining letters from the "Bonneville" and "Catalina" nameplates. Many of the Pontiacs made available for magazine testing were equipped with the Bobcat kit. The GTO Bobcat accelerated 0-60 mph in 4.6 seconds.
The precise components of the kit varied but generally included pieces to modify the spark advance of the distributor, limiting spark advance to 34-36° at no more than 3,000 rpm (advancing the timing at high rpm for increased power), a thinner copper head gasket to raise compression to about 11.23:1, special intake manifold gaskets to block the heat riser to the carburetor (keeping it cooler), larger carburetor jets, and locking rocker nuts to hold the hydraulic valve lifters at their maximum point of adjustment, allowing the engine to rev higher without "floating" the valves. Properly installed, the kit could add between 30 and 50 horsepower (20-40 kW), although it required high-octane superpremium gasoline of over 100 octane to avoid spark knock with the higher compression and advanced timing.
The performance manager at Royal Pontiac was Milt Schornack. Adhesive stickers were added to advise onlookers of the fact that this GTO was a Royal Bobcat.
Optional with the Bobcat package was an extensive re- machining of the cylinder heads and block to "blueprint" the engine—that is, carefully machine the components so that their critical dimensions met the original GM factory blueprint specifications.
Who would have thought in 64 that the receipt from Royal Pontiac would be worth an additional $40-$50 thousand 50 years later.the last time I viewed a gto that was being sold as a royal bobcat with documentation, the price was $90.000. it was a '64 coupe in las vegas, Nevada.
