| Same cam, different car |

Back in my street racing days in the mid 60's, a friend of mine had a 1963.....let's just say that it was not a Ford. However it did run great. It had a 4-speed with a 3.70 posi rearend. We changed the stock hydraulic cam to a big solid lifter one and it ran even better. After he tore out the 3.70's, we put in a 4.11 and the car became a serious contender on the street. Then came the night he crashed it street racing.
After he healed up from his injuries, we put the engine alone in a convertible that had an automatic and stock 3.08 rearend. Same complete engine with no change to it at all. Although the engine still sounded strong, that car was one of the biggest dogs I have ever rode in. We wound up putting the original 2bl engine back in the convertible and he sold the good engine to another guy who put it in a light weight '36 coupe with a 4-speed. The coupe became one of the fastest cars in the neighborhood without doing anything to the engine.
That is when I learned that if you do not have the proper rearend gear and a lighter weight vehicle, you do not want to go very wild on your camshaft selection. Heavy vehicles with gears around 3.00 need a very mild cam with bottom end torque to get them moving.
