I shift the car at 5,500rpm and haven't had it above 90mph in 3rd gear. I am curious about it's 1/4 mile time and mph.
However sticking the 3.42 gear in it will diminish that quite a bit, until I get tired of the 3.42s and stick a 4-series gear back in it, lol.
One of the reasons I like the 4.56 gears is because this car feels like a rocket ship driving it, like it could "almost" keep up with my 455 powered Skylark, but in reality it has zero ability to keep up the the Skylark. The Skylark has 3.89 gears, but I've ran it as low as 3.08's, and I did like the 3.42's in it, but it left a lot of ET on the table with the 3.42's because the rpm drop and crossing the 1/4 mile finish line at 4,800rpm in 4th instead of 5,800-6,000 rpm, basically waaaay under the max power band with the 3.42's. For 1/8 or 1/4 mile racing, always optimize the gear for the mph you expect to run to the red line of the engine. Automatics with good stall converters work the best, but I like rowing my own gears.
