3:55 vs. 4:10 Gears

[Rider90]

What differences should I expect? Anyone know any numbers about RPM at 70MPH or 80MPH? Any information is useful as I am considering this swap in my Vic...

Two different cars bud.

The DOHC and taller tires like 4.10's ALOT more.

Hey Chris, man I just checked UPS tracking and it hasn't changed a bit in two days... :( Thanks for the reply in this thread

Approx 300 rpm @70mph. Look under FAQ and also do a thread search.

Get more bang for your buck and get the 4:30 gear.

You all have to remember that his motor is only a SOHC, which although won't make too much of a difference, but his stock tire height will. 4:10's in your car will be more dramatic effect than it is in ours.

[merc406]

What tire diameter you guys running?

[Rider90]

225/60R16...

[merc406]

4:30's will be fine for your ride.

[Rider90]

I've been hearing about a new chip and such for shift points...don't have that much money now...but maybe later on down the road. Thanks everyone!

4:30s the only way to go!!!!!!

[RocketCouch]

no 4.10's, no 4.30's Your Crown Vic will not like it. Been there, done that. Wouldn't do it again...
