stall or gears

**LT1 > LS1** · 08-08-2008, 06:28 PM

I was wondering if I would loose a lot of gas milage with a 2800 stall, and 2.73's.

as of now, I was really considering 3.73's because I can always do a stall later.

its my DD, and I want a little more scoot. right now, I can never get wring out 2nd gear with out goin way over the speed limit, and with 2.73's maybe I could use the rpm's more.

I quit carin about gas milage, but I would still like to get somthin with 2 digits if possible.

3.73 gears/stall won't effect fuel economy that drastically. You'll be fine. I had 2.73's in an old car so I know how much those gears suck. The 2800-stall will be perfect for you, considering you have a light bolt-on daily driver.

Worried about gas milage buy a toyota. Get a stall and 3.90 gears for an auto. Don't settle for anything else!!!!!! 4.30's here with a 6 speed daily drive it every day and still get 23.5 MPG with mods listed.

Do the stall first. Gas mileage will stay the same on the freeway.

Another vote for stall.

I never ever ever touch freeway.

I am looking for my car to pull a little harder on the top end. will the stall have any affect besides helping the launch?

a stall and higher rear gear will give you less pull up top.
best bet to do first is a stall converter and nothing less than 3000 rpm

its an LT1. thats where it makes torque. its peak is like 2400 rpm.

I was gonna do a 2800 rpm tops. I am not doing heads on this car......but I will do a cam waaaaay down the road

2800-rpm stall is perfectly fine. It will match up nicely to your mildly modded LT1. This comes from personal experience as well.

so, when I upgrade the stall, it will pull weaker, but pull harder on the launch?

I am concerned mostly about 50-100 ish. I am trying to keep up with a 03 mach 1 stang. we havent lined up yet, but I wanna be ready. he ran a 14.0 at the track.

13.70's-14.0 is about right for your buddies Mach 1. From a roll it should still pull decently even considering it's a 4R70W-equipped auto car. Aside from the stall and gears I would recommend the cold air intake to go with your cat-back and you should get 'em!

**LT1 > LS1** · 08-09-2008, 06:57 PM

sweet. I was thinkin of doing a intake and TB splitter here soon.

yes, his stang is an auto. well, I enjoy driving the car as it is, and I am gonna make it louder here soon too, via cat modifications.......lol

TB Air foil has proven good for a couple horsepower. I guess every pony counts huh, plus thier cheap. The stall, gears, and headers are going to give you the most significant gain though.

**LT1 > LS1** · 08-09-2008, 07:21 PM

I think the gears will help me pull on the top end more. and thats what I am concerned with. plus, I can get the gears, intake and foil thingy for the price of a converter.

so, I think I will do that. intake, TB splitter, and rear gears. should I get 3.73's or 3.90's?

The stall will make the car fun as hell to drive. But FYI you loose top end with gears.. With 3.73 I top out around 150/155 ish... Only way to stretch your top end out is with 2.73's... If you want to get to that top end quicker either F/I or Nitrous. I would just do a stall IMO if I were you... Or undestand that if you do gears you will loose top end.

**LT1 > LS1** · 08-10-2008, 07:30 AM

I know I will losse top end, but I dont go anywhere close to 170 mph anyways.

I will mostly do 1/4 mile style racing, and occasional stoplight stuff. getting to the to 150 with 3.73's should take less time then with 2.73's right?

I think what you are looking for is to get up in the powerband quicker. Yes the stall and gears will take care of that.
