Hey, I recently bought a 97 SVT Cobra convertible, and was wondering what rpms you guys with 4.10's shift at while daily driving. What are the rpms while cruising on the highway? The gas mileage is already bad enough, and I have 3.73's left over from my 5.0 that I can use. If it's not too much of a difference I'll go with the 4.10's.

Every car is different u need to dyno it to find where your power drops off then u will know when to shift. Where u make peak power and then it drops off u need to shift.

I want an idea of what rpms people with 4.10's shift at so I can tell how much the gas mileage will change.

as far as daily driving shifting, you arent goin to be powershifting all the time and wot shifting, so the shift points should be the same as your 3.27 motivated rear end. possibly a little higher till you get used to how much faster it revs.

gas milage shouldnt change that much prob 4mpg at the most under the stock mpg, and the shift points are going to be different with those 4.10's, i know with my 94 cobra as a daily driver i shift a 2500-3000 and when im racing i shift at about 5000rpms which is where my hp and trq starts to fall
