| RE: Rearend Gearing |

Exactly right Gerry. In most cases a bigger cam, intake and headers are useless unless it is accompanied with a rearend gear change. I know of many instances where someone took a fair running car and slowed it down with a bigger cam and intake all because they did not install a set of gears that took advantage of the modifications. I also know of a few who changed the gears first and could not believe how much their cars acceleration improved without any other parts swap.
Even though this is a FE Forum I must tell the story of a friends Ford back in the early 70's. He had a decent running 65 Mustang with a 289/200 4-speed. He lightened the car as much as possible without being obvious. Then he installed a set of headers, a strong set of valve springs, and a larger 2 barrel carb off a 390 Mercury. The only other mod he did was to install a set of 4.62 gears with a posi in the 8" housing. This car was very quick and a huge fooler with the 2 barrel carb. Of course he was always able to get a few car lengths head start with the 2 barrel. But the 4.62 gear was what really made the car run strong. He won many, many races in the early 70's on the street. |
