Price them out at your local auto parts store. You'll only need to replace the front pair. The rear pair just monitors the functionality of the catalytic converters. It's a very simple job.

Just curious what do you guys think my car will run quarter mile. It has mac cai, 78mm throttle body, tf plenum, no cats, h pipe blowmasters, 1.5in drop springs, 3.73 gears, full p.i swap with rebuilt ported 3 angle valve job heads, drag radials, no spare tire/jack. Just curious what i will run and im pre far from a strip.

Also o2 sensors can cut down on your time? my rears are mil deletes but front are throwing a code?

If your front O2's are to the point of throwing a CEL, they're not controlling your AFR too well. Yes, that could certainly effect E.T.'s.

If your front oxygen sensors are giving you a check engine light, they are obviously FUBAR. Replace them.

were the 4.10's in the car before you got it or did you install them because ive talked to ford mechanics that say your on drugs if your doing 70 and only turning 2200 rpms.

Agreed. If you're running a stock tire diameter (25.68"), 4.10's will net you ~2500-2600 rpm at 70 MPH. 4.10's with 28" tall rear tires or 3.73's with stock height rear tires will both be around 2300 rpm at 70 MPH. Those numbers go up a bit if we're talking about an auto, too.
