Anyone DD a 400 trans? Just like the title says. Im thinking of using my 400 I have sitting in the shop in my DD when its going. Be using a 4000 stall(maybe 3800) and gears. Probably go 3.73 but depends on how the car runs. Anywho, who here uses a 400 in a DD and hows it do?
Depends on what form of FI. Turbo cars get better gas mileage than blower cars. I myself will be running a Procharger on my setup. 3.46 gears and 26" tires with 4200 stall. Semi-DD, lol. My old NA setup had so much overlap I only got 16mpg on the highway. I averaged 12mpg in town. With the new boost friendly cam I expect to be a little higher than the old mpg numbers. Maybe.

I will be runing a custom grind cam somewhere around 23x and 60x so won't be as bad as with your cam lol. Only power adder would be n2o. No blower or turbo. Undecided on what gears yet. Just thinkin of running the th400 because its sitting in my shop and trip over it everyday. Might as well use it lol. Anyone wanna share their setups with this trans? Thanks guys
RMVB th400 w/brake, 3000 stall, 9" 3.70 gears, turbo 5.3 at 17psi
Its at around 3000rpm at 65.... doesn't bother me a bit driving it around, drive it every day there isn't snow on the ground, and i have to drive quite a few highway miles to get to work.

I was thinking of going a turbo setup but wasn't sure how involved it was for a DD. I will be running a 5.3 also. What cam and heads are your running? If you don't mind me asking.

Not bad at all!!! Thats really awesome. You choose the 5.3 for the compression or did ya blow a 5.7? lol. Im going that route purely for price. Either leave it low compression and turbo or use 5.7 pistons, mill the heads, and run n2o. Prolly go n2o for the simple fact its cheaper. Hell I haven/t officially bought the car yet but looking at all my options before I spend any money. Hate doing things over again cause of rushing it or bad choices.

ya i blew my 5.7, killed the #7 ringland, pretty common lol... chose the 5.3 because it takes to boost so well, and is just do damn cheap.
are you buying a car off tech that is an unfinished turbo 5.3 project???

No buying a wrecked TA for cheap out of texas. How mush of a pain was it to install the front mount? I was under the impression that's its really expensive to do a frount mount turbo kit. Even if you build it yourself.

With the Power LS Engines make, I would just stick with a Turbo 400 because they handle so much more power than a $2000 rebuilt 4l60e that can only handle 600 hp 700 FT LBS
Your losing over drive so expect to lose 5 or so mpg depending on what stall you run.
Is it worth the head ache of building your 4L60E every year or two?
Haul ***!
