Cobra has offroad x, Cai, catback. Z28 bone stock ... I'm thinking cobra has an advantage Do to the auto tranny in the z28 .. how would this pan out from a roll or a dig ?
I'm thinking the Z28 wins by probably a car length in the quarter. The Cobra needs gears, like 4.10's, or 4.30's. Exhaust is just going to make it sound good while losing.
I'm about to do 3.73s , underdrives and a sct handheld think that will help? I drive this thing a lot or is do 4:11s
dont use the 410s if it sees alot of highway time, while they r stop light killers, itll kill ur mpg....ive had many sets of 373s and 410s, every1 says the 430s are the way to go on these modular....idk arent there 390s out now, mayb theyd be best since its in between??
You won't get worse fuel economy by going with a 4.10 or 4.30 gear. I had 4.30s installed in my old 98 and it got the exact same highway mileage as it did with stock gears and it got slightly better city mileage than the stock gears.
