Rear disc K-code intall

[88grandmarq]

Finally getting around to installing the rear disc Kcode in Brian's 89 town car.

Yesterday we made some good progress, installed new pinion and axle seals, new e-brake shoes and rebuilt the traction lock. then we got the old rear end out of the car just before dark.

Weight

Hey grandmarq, do you by any chance know how much that rear end assembly weighs? I'm talking about the entire rear assembly on the ground in your bottom picture.

I would guess 150-200lbs

I would guess 150-200lbs

that would be my guess too.

doing the 8 clutch rebuild? or the new different stack pattern?

[rct071365]

Wow I would have guessed heavier, thanks!

Just the factory clutch rebuild. Bought a kit off ebay that I thought was FRPP, but instead was some chinese crap, the clutches were good but the plates did not fit, as the spline teeth machining job was inferior, so watch out guys. Drove her 7 hours home no problems, surprised a few cars on the highway, and got decent mileage (20mpg) for doing a few 0-85+ blasts and some extended 80mph cruising.

edit: got it from diff-man on ebay, apparently he sells Motive Gear aftermarket stuff. Make sure your stuff is FRPP! http://cgi.ebay.com/ebaymotors/ws/eB...1626&viewitem=

What kind of fuel economy were you getting previously?

What kind of fuel economy were you getting previously?

Around 21, but that was doing ~65mph all the time and concentrating on getting the most out of the car. Overall mileage didn't change much with the higher gear. Eric also fixed the PCV system in my car, I didn't have a crankcase vent hose going from the oil filler neck to the TB, it was just capped off, causing oil and vapor to build in the crankcase. Also my fuel pressure regulator was T'd with the EGR stuff on the pass. fender well, and now it has a dedicated port on the Exploder upper intake. Honestly at this point, I would rather have e7TE heads and HO intakes over my GT40 heads and Exploder intakes. Seems to lack lower rpm torque and run rich with the SD computer.

[gadget73]

rich? Usually the complaint is it runs too lean and pops and does all that other bs. What cam are you using? If its the HO stick, those are just weak under about 2500 rpm. Better flowing heads and intake seem to exaggerate the boost they get over 2500 though.

[1980c10]

It's true the stock H.O. Cam is kinda light switch-ish in are cars. If I were to guess I would say your gt 40 head and exploder intake combo is making more tq. Across the board even low rpms than a regular H.O. Just that cam making it feel turdy.

lightswitch is right.. my car is slower than shit off the line and then throws you back like someone hit the afterburners.

the 3.55 gear certainly helped, especially on the highway now I don't have to shift into 3rd to get power enough to pass. It's a turd under 2500rpm but up around 5000 she's flying. With 4.10 gears I bet she would be a beast though... she has ALWAYS ran rich, I swear I have run close to 20* of timing and had no detonation. I may have a shifted balancer though because I couldn't believe such a thing would even be possible.

Rich? Check the following--stuck injector, bad O2 sensors, ACT, ECT, MAP (vac line condition).
