neil,
great story and congratulation to you Wagon, again and again.
Concerning the final drive and the times, changing from 3,07 to 3,27 will give you better acceleration in general while changing to 2,87 will give you higher max. speed or at least lower rpm at the same speed.
The time for 1/8 or 1/4 mile depends also on the shifting points and the gear you'll finisch.
If you shift the engine at 6500 (don't know the numbers for your engine) you will get appr. 68mph in second gear with 3.07 but 73mph with 2.87 final gear.
Doing the race with only two gears with a longer diff (2.87) will do better than using a shorter diff (3.27) but having an additional shift from 2nd to 3rd gear.
On the other hand this optimizing can only be done for one special situation 1/4 OR 1/8 mile OR high-speed racing and on and on. As you know, professionals adapt the gearing for every specific course to get best results.
Do you know the program "car test"? That is made for exactly this purpose: playing with numbers. It's great and helps you to decide, wich gearing will fit best. Have a look at it at the site of
car test software .
best regards,
