1970 Buck Stage 2 455-cid

There was also a rare Stage 2 option produced. This was a dealer-installed package that was first offered in 1969 and included a cam, headers, intake manifold, high compression forged pistons, hollow pushrods, and some calibration changes to the ignition and carburetor. If the car was ordered with the Stage 2 package, the parts were shipped with the car but were installed at the dealership. In 1970(?) the Stage 2 package included special, round exhaust port Stage 2 heads, matching Kustom brand headers, a radical cam, high compression forged pistons, Edelbrock B4B aluminum intake, and other equipment for racing. Few stage 2's were ever used on the street and Buick only ever factory assembled 15 Stage 2 test units. One of which was a factory GSX test mule with 4 speed manual transmission used for speed testing. The Stage 2 package's existence was not made public until 1972 when the Stage 2 parts could be ordered in any combination. There is little documentation about the 12 Stage 2 cars that were sold. One was campaigned by Kenne-Belle and the other was knows as the Jones-Benesik car. The Jones car was the one that was known to have been delivered as a Stage 1 car with all the Stage 2 components in the trunk in GM boxes.

Output and sales for the assembly-line cars were down after 1970 largely due to reduced engine compression ratios and a change from gross to net horsepower ratings. In later years, air quality regulations further limited the power in part due to the addition of catalytic converters and single exhaust pipes. However, Stage 2 parts were available over the counter although the stage 2 heads were discontinued after about 75 sets were produced. The discontinuation was due to porosity problems with castings.

So, if a normal Stage 1 is said to be between 360 SAE Net and 500 HP, of course it's argued what it is. And you add Stage 2 parts your defiantly looking at a massive increase. A replica price tag from a Buick Dealer in Flint showed the engine pushing out 625HP.
