I am currently researching parts for a 9" ford rear end that will be bolted under my 76 Skylark in place of the stock 7.5" pegleg rear end. Once I get the 455 & sp/400 installed, this vehicle will be street driven for awhile along with some strip time, and will see mostly strip duty later (brackets) as my budget permits. I am going to back-half the car when the rearend is installed, (4-link, tubs, and 8 or 10 point cage) so room for larger tires will not be an issue when I bracket race it. I am looking at using a Detroit locker and a set of Richmond 3.89 street and strip (8620 steel) gears, 31 spline axles, and a Strange nodular iron center section. I have never driven a car with a Detroit locker before, and I wondered if the cornering noise was too much to put up with on the street. Would a factory ford "traction-lok" unit be better suited for street & strip use until the car graduates to strip-only status, and a change to a spool and drag gears is necessary? Could anyone here with some experience with these units give me some advice on which would be better suited for my application? Any help would be greatly appreciated. Thanks, Randy
Forget the posi. They are good for mild street applications ONLY. Your options are detroit locker or spool. Personally, as long as your a good and smart driver, I wouldn't have a problem running a spool on the street. I've owned an old Mopar with a spool and always drove it on the street. Never had any problems. Drove my Uncle's old Charger with a spool and again, never had any problems. As long as you use your head you should be fine. Plus, spools are a few hundered cheaper than a true locker. Also, NO MINI SPOOLS! Realistically, it comes down to two things. Cost and if your comfortable with running a spool on the street.
