Re: 2.73's and a stall

if you were to do it, it should be no more than a 2800 stall at the MOST...maybe go with a 2400. AND you would HAVE to add a tranny cooler to prevent the excessive heat from the TC slipping so much. Most people say that you shouldn't put a high stall TC with 2.73 gears.

I run a 3200 with my 3,23s, cars perfect on the street, no issues.

Re: 2.73's and a stall

can anyone confirm that there is extra heat buildup on a stalled 2.73 car? i hear it from some, and not from others...

Re: 2.73's and a stall

Adding a stall will create extra heat no matter what gears you've got. Just be sure to run a tranny cooler and you should be ok.

Who says that? I am running a 3500+ stall w/2.73 gears. It may not be the most optimal setup but it can be done! I am only doing it because I like the responces I get when people see the time I run and I tell them I still have the stock 2.73 in it!

Actually it has gotten so fun, that it has become my current goal. I want to be one of the fastest stock bottom end, 4l60, stock 2.73 rear, stock suspension cars in that fastest LT1 list running around!

But either way, I think it is fun to beat someone and see this look when I tell them I haven't really done much and it even has the stock 2.73 gears!

Re: 2.73's and a stall

how do you like stop/go traffic with that settup, and how is traction too? i always wondered about that because you still have some nice launching capability, but without some of the downsides of lower gears..

Stop and go traffic kinda sucks sometimes, and gas milage in those situations suck too, it seems like it is always slipping because it never gets full throttle, so it never gets into a locked position. I am not refering to a locked converter, but you know when a stall speed has not been reached it feels like a slipping clutch, more or less! Under part throttle it stays around 2K rpms or so. You get that sensation more with the 2.73's then with lower gears because the rpms never go up as fast! and in responce to your comment above about the more heat yes that is true! I have a high rated cooler and also have a 160* t-stat and I bring the fans on about that time too. So, my temps never get too high!

You do or don't have a locking converter?

Re: 2.73's and a stall

I put a 2800 stall TCi in my Monte when it had a 350 with a th350 and the stock rear with 2.56! I droped a 1.1 secs in the quarter, best $200 I have spent in my LIFE! It was nice b/c I still had the highway b/c of the long gear, but I could load up the converter and the motor loved it, no more super long gears.

I do have a lock-up converter, but if you know anything about converters they don't lock up at 3500 rpms if it is a 3500 stall, in our cars the lock-up is computer controled and is dependant on throttle position and MPH. Any converter will slip untill it reaches its stall speed then gives that feeling of full momentum. Just drive your stock stall and pay attention to it to really see what happens. When you are stopped you hit the gas and RPM's go up to a point, dependant on how hard you hit the gas. If you hit the gas softly like in normal stop and go situations the stock convertor goes to about 1200-1300 RPM's do you really think from a stop your engine needs to be going 1300 RPM's? No, it sits at 1300 until road speed matches where the RPM's should be, all that time it was slipping.

With my converter if I hit the gas barely to make it move slowly the RPM's go to about 2000 and sits there longer untill I reach the road speed to match what 2000 rpms should be, but it actually shifts before that because the shifts are done sooner with less throttle. So in normal stop and go traffic, my car just stays around 2000 rpm's when moving.
Something like this (these are estimated numbers just to show what I am trying to say);
1st gear 2000 rpm's from 0 - 5 MPH,
shifts to second stays 2000 from 6 - 15 MPH,
shifts to thrid and stays 2000 from 16 - about 25 MPH,
I am normally slowing down before I get much faster then that in traffic!
This is why I say it is always slipping in traffic!!

Re: 2.73's and a stall

The reason people say you get too much heat with a high stall and high gears is if your crusing speed down the highway is less than your stall your converter is never fully "locking". I had the same problem with my old setup with a 2800 stall and 308s with a turbo 350. Thats why i went to an m6

Re: 2.73's and a stall

It depends on the spead you are going if it is locked, and if it isn't locked then you are also not doing the RPM's that would be full stall, in my case around 3500 RPM's then it is slipping...

I cruse on the highway at about 55 MPH and 2500 RPM's the conveter locks around 60 - 62 MPH with less then 25% throttle (cruising) when I hit that lockup speed my RPM's drop to about 1600..
And in traffic it is sometimes hard to go fast enough to have the conveter lock!
