id like to look at the pics.

how is it on the street?

i have the borg warner type with springs.looking online they are about $1300 complete ready to bolt in. how much to rebuild one ?

got it all back together with a 315 g u joint. deffinately gonna get better gas milage and slower et in the 1/8, but im good with that for now. at least i can cruise for the rest of the season.it smokes one tire pretty easy with the open diff,so im gonna take it easy on her and make it last...

update, i did find a few small chunks in the housing with a magnet.so i cleaned everything real good and its going back together today.the 489 yoke is 3 3/4 across and the 741 is 3 1/4 across. soo, do i need a 315 g u joint ?

i pulled the 489 carrier out of my 8 3/4 today.its a 3.23 sure grip,and it started making noise at the drag strip last week, so im putting the stock 741 carrier back in with 2.76 gears for now.i looked at it, and the ring and pinion look fine, but the spiders are damaged.looks like a few small...

me too, i talked with my buddy, and he said with the weight of the car and et in the 1/8 it equates to 40 hp.not bad for an hours worth of work.he said if i could find some 3.91 gears i would be in the low 8,s .guess what im looking for,lol. for now, im gonna put a set of 2.76 in and it will...

huh , i figured some one would comment on this by now.unless you are all out drilling your air bleeds or something?

went to the drag strip today.good news is the car picked up 2/10 in the 1/8 .bad news is i ate some rear end gears.looking for some 3.55 but i do have a set of 2.76 to use for now.anyone close to nh ?

soo, after crusing with the car today,i decided to work on the pvcr,s.they were .o36, and i ended up drilling them to .050.that is as far as i went, and it also made a big difference.i also opened up the secondarys a little to clean up the idle , and it worked, but my idle is about 950 rpm in...

drilled the bleeds, and it definitely cleaned up the wot.car runs better at cruise and off the line.still a little rich at idle, gonna work on that today and see if i can clean it up a bit.im glad i drilled them out to what i was told, it helped me a bunch.

i called holley, and they told me my carb had .025 inner bleeds on the secondary side, and .028 on the outer.he also said the primary are .028 inner and .078 outer.if the front outers are at .078, then ill probably have to put a wire in the ifr,s , or change the metering block to a smaller...

i have to get it back on the dyno for that,i dont have a wide band, so right now im tuning by reading the plugs.i will deffinately let you guys know how it turns out after i drill them.

i have tried just about every configuration with jetting from 72 front -76 rear to 84 front 88 rear.2.5 power valve to 6.5 power valve.i had two different metering blocks, the stock metering block had .063 holes in the pvcr,s, and the other is .036.the smaller pvcr,s work best with the 81 front...

yes,both low and high speed.it is rich on both right now.cruise is perfect, but too rich at low and high.

i have a good understanding how the fuel cuircuts work,just never touched the bleeds.but, i was told by a pro builder to drill them. .032 on all 4 out back, and .032 in the front center, and .078 on the front outer.he knows his #$%^ and has helped me get my car running mint.i think i should give...

im sure the gears help with the mileage. im gonna give it a shot with the 850 double pumper, what do i have to loose?

only because a vacuum secondary is more forgiving on the street,i might just try the double pumper anyway.
