125mph give or take and the wildest gear that can accomplish that is a 4.56... this is a request to run sub-7.0 in the eighth. 5.38+ gears and transbrake needed for that but will fail to make in another 660 feet before finding the rev limiter. This will only be accomplished with large port heads and nearly a 7K RPM power peak. I do however wish you luck, but this goal won't land in the realm of a NA "street 318" at 3,000lbs. Not to sound like the peanut gallery but... a 360 will do it with less head/gear/money while still getting milkshakes after and you know that! haha
