How to identify a close ratio to wide ratio 833
I have an early 66 to 67 4 spd I was wondering how I can tell what ratio trans it is. I'm running a 3.08 rear so it tends to buck in 1st and 2nd at low speeds.
It takes a pretty big street cam to buck in first. To buck in second you are either lugging it, need better gas, or your tune is way off.
You wanna talk about the tune first? Might save you hunting for a tranny......
There is only about 7% difference from the 2.47 to the 2.66. This is less than the difference from one rear chunk to the next, below 3.73s.
There is 16% difference between the 3.09 and the 2.66; but second,third, and fourth are the same. And outshifting the 3.09 will drop the rpm to lower than the 2.66 at the same rpm; so there is no cure here.
That means; if your tune is spot on, and your gas is top-quality, and you are not lugging it, then you have one of three options;
1) you need a bigger rear gear, or
2) you need a smaller cam,or carb, or
3) you will have to live with it.
I wanna talk about the tune,lol
