Other than the 7 torque whats the difference with these 2?

Here is JR's page for each. The 8450 has been discontinued for a while now. But it is still a great servo. I still have one and use it often.

JR z8800s

Looks to me like other than the extra torque, the case size and weight is a bit more on the 8800s. But not anything noticable.

so if u had a choice of the 2 would it really matter which u take. or just go with which ever u can find cheaper

In a car/truck I doubt you would notice a difference between the two. I would get which ever is cheaper for you. If it's the 8450, go for it. Parts are still available for it through JR.
