changed rearend in my monte...wow

[V]

ok I FINALLY got some time to swap the rear in my monte, well 90% of the swap is complete, i still need new shocks, brakes and fill the diff. Anyways ever since i got the car running and on the road, the car has been a dog off the line and i could run 2nd easily to cruise at 50mph, the sluggishness I chalked it up to the dual 3" exhaust flowing too much. But then i remembered that the current rear had junkyard writing on it saying "86 regal". I then thought maybe it has 2:73 gears and with the larger diameter tires and the T5 tranny, maybe thats causing it partly too. The T5 came from an 88 iroc with a 3.45 rear, so the 2:73 would be an issue, anways i pulled the 3.73 posi rear from my 88 monte ss. before i pulled the current rear i opened it up to confirm the gear size...well...with 41 ring teeth and 17 pinion teeth i found out it has 2.41 gears. wow, im suprised it ran like it did and not worse. Once i get to drive it with the 3.73 rear i think i'll be very happy and maybe i wont have to swap the long tube headers for the edelbrock shorties i have.

sounds good, nice finding out that what is being swapped in is even more better than what you thought was there lol

Heh....damn those 2.41s. My brother's '79 Malibu has those gears, and he's also planning a 3.73 upgrade.

i drove the car tonight, wow, HUGE difference, before with the t5 it would almost stall the car when starting off now i can spin the tires at will. The car is so much easier to drive now and you can feel the power the engine is making. A rebuilt 350TPI motor, T5, and a 3:73 rear makes for a fun car, now i hope my GF will like it, haha. Tomorrow i think i may change the headers still though, im just not happy with the sound of the exhaust, too loud for my girls daily driver.

I've had several old Camaros(67-69) that came with the Powerglide 2 speed automatic and 2.73 gears! You could take those cars out to 70 mph in 1st gear but they were complete dogs off the line. Switch to a TH350 3 speed automatic and 3.55 gears and they came to life without killing the highway cruise speed. 3.73's and a 5 speed should be a pretty cool combination.

Yep, about 2100 at 70 mph. Very livable, and not bad on gas!

my brothers cutlass had 2.41's...well...probably a couple times in retrospect lol
