I would go for 3.92
Better acceleration

3.92 would give you roughly:
6360rpm @ 30 in 1st
2390rpm @ 30 in 3rd
2850rpm @ 60mph in 5th
3330rpm @ 70mph in 5th
4760rpm @ 100mph in 5th
and so on..... 3.62 lowers those rpm's by about ~8%

I have a 3.92 and 195/50/15's. Cruising at 60mph is just under 3k rpm, which seems about right to me.

thanks for the quick replys
I have a 3.92 from the donor car but thought it might rev to high as the donor had 185/65/14 and i am going to use 195/50/15 which has a smaller
dia?
it seems that 3.92 for a fast getaway or 3.62 for crusing then

Have a play with this, you can try different diffs and tyre sizes
If you can keep you head, whilst all others around you are losing theirs, you are not fully aware of the situation
