Gear choice

Do you have a 2nd car? I would go 3.55, let the engine breathe. In CA freeway driving most areas it's 65MPH and if no traffic, you better be driving 75-85 in the fast lane or you will piss a lot of people off so now you're in the slower lanes and you can cruise along at 65-70. other option what I did when younger & speed limit was 55 on freeway, I traded my 3.23 for 4.56 and still drove all over then I started my 8 3/4 collection of other 3rd members, it takes less than 1 hr. to swap gear sets, with a few choices if you want to go a long trip swap in some freeway gears you can still do it with the 8 1/4, will just take a little longer or swap in OD trans that you have.
