Is that a good buy for my set up or is there something better?

I have an old style Locker in my 66 Fairlane. Noisy, clangy, bangy thing.I have a newer style "soft" Locker in my 63 Galaxie. Now and then it'll click but it's much easier to live with.

Detroit Lockers are good. ------------------ Alex Denysenko Co-Administrator and Moderator NHRA/IHRA/SRA member and licensed Superstock driver NHRA and IHRA SS/LA & SS/MA National Record Holder '00,'01,'02,'03,'04 &'05 First SS/MA in the TENS!

The Detroit Locker is 1 step below a spool. It is the the best for max strip traction, and still be streetable for limited use. Other non-locker types are better for a street car, but not as good for the strip since they do not provide equal power to both wheels while under power, all the time. The 2 negatives of a locker, are some noise and you have to be carfull feeding power to them on the street while turning.I am putting one in my car next month. ------------------ 1993 Tbird 393 stroker, 3500 RPM converter http://members.tccoa.com/393bird/

Should be plenty stout for a street car or a street/strip car. I'd put in more gear, but that's up to you. I don't drive on the street too much and don't mind 4.11s.

3.89 is a good "general purpose" gear except for cross country driving.Keep in mind that tire diameter will change your effective gear ratio. Tall/30" tire will be like 3.50 Short/24" tire will be like 4.11 These aren't exacting figures, just the direction things take when you change tires.

Thats my set up... 351W, 5 speed and 3.89 with detroit locker. Mostly street driven, I wish I had gone with a Traction Lock instead, no problems, just noisy, works well. ------------------ Stuart MCA #48902 M&M #1091 67 stang 5 speed, 351W, Edelbrock Performer RPM package my photo page

My tire size is 18" rim with low pro tires. How high will my rpms be with that?

gearing is a real subjective thing. With those 18" tires you'd probably be the near stock tire height, 25-26". I think anything in the 3.25 to 3.89 range is fine for all around use but if you have an overdrive going to 4.- is OK.
