diff ratio ???

[burner]

Can anyone give some advice on gear ratio`s in the rear diff ??? mine currently is a 4.5 lsd but have fitted a v8 lump and the revs seem high to get any decent speed on the motorway !! any ideas what ratio would give a better top end ????
cheers

Normally they'll have a 4.10 ratio in each diff.

Due to the power of your V8 you could go lower than this - check out this site
