Diff gear recommendations
Cool! :thumbsup: Ride shotgun! As I mentioned the engine runs great but would like to add oomph. I probably drive 80-90% street or very short highway stints.
80-90% street, and very short highway trips.
Sounds like 3.73s to me. I like to see at least a half ratio change to make the expense worthwhile. Add a converter with about 500-750 rpm more stall than you have now (500 would probably be best) and you will have a completely different car. If you find that the 3.73s seem a bit too much, run the tallest tire that will fit in the wheelwell.
Edit: my performance street car runs a 4500 converter, and 3.91s. My other car, I bought a 4.10 pig to change out the 3.50s, so take my advice with a grain of salt, or two.
2nd edit: Rusty's #41 posted while I was typing. I agree.
3rd edit: don't be afraid of the "weak" 741 reputation. Check out Dr Diffs comparison of the 741, 742, and 489 pinions. Smallest part of all three is the same. Extra metal elsewhere doesn't mean much. Remember weakest link. Weakest link of all three pinions is the same.
