Long story short. The 9" full float rear end I want has a 11 week lead time (Thanks Biden). While I know transmission ratio and engine torque curves are all taken into consideration. I'm trying to narrow down the rear end ratio that comes the closest since I need to buy today to have it 3 months from now.
Engine is going to be a high revving 363 or 427. I know both have different curves but we'll be bouncing 3500 RPM and up on both.
Tranny is going to be a 5 speed with most likely the following ratio's (or pretty darn close)
1st 2.90
2nd 1.90
3rd 1.37
4th 1.00
5th .58
I will have the power and suspension to handle 180+ mph, light weight to handle a higher ratio and of course the brakes to stop it.
For the 9" I'm thinking the 3.50 or 3.40 are best, one given slightly higher top speed other faster accel. 3.25 is too low and 3.70, too high. Basically looking for opinions, what you run or better yet validation. If I have to change it down the road if I really need to then fine
Thanks
