Anybody running a 4+3 behind a stroker ????
I am in the process of building a 388 stroker , (nearly compleate and estimate 450-500 HP) and plan on hooking it to a 4+3 trans. (3.07 Dana 44)I am curious as wheather or not the trans will hold up under full throttle acceleration (when the tires finally hook up). Any advice ?

Mine still works just fine. I've probally got about 70+ runs on mine with slicks. The only gripe I have about it is that they don't seem to like to be power shifted.
As long as you baby the OD you'll be fine.

Ky: The 4 in the 4+3 is a strong unit (ST-10). You probably wont do any damage to it even trying...
As for the +3 part... Just be careful of when you put it into OD... On my car I am wiring the OD unit outside the computer, so it will only turn on when I tell it too, no other time... So that I can make sure its never under strong load/accel.
You may want different gears, depending on use of car... With LT1 intake, off hand I would guess 3.54s or 3.73's would be most likely canidates... (3.54 is going to be my choice on mine, with SuperRam)

Sorry about that ( :lol: ) stealing your name, even though I'm in NC I'm originally from Owensboro, and here in Carolina there's not many people advertising for Kentucky (think Duke might have something to do with it ... my wife works ther and wears UK stuff during the tournies.) :cheers:

Thanks VetteRacer, I'm planning on wiring the second gear switch plug (jumpering it) so the ECU will think the trans is always in second, that way the ECU won't automatically go to OD unless I push the button. As to the gears, I'll wait and see but you're probably right, I'm thinking the 3:73 would make a good rustang, C5 eater ! :smash:

Other wires on the tranny that I am going to have are the reverse lights and speed sensor. The gear sensor is not going back on.

Guys,
Why don't you remove the Tan/Black wire from terminal A7 on the ECM and then run another wire to it that switches 12v on and off.
C7 which is Black/Light Blue is the Overdrive Request. I think that is the one O/D switch runs to so when the ECM sees 12v hit that terminal it fires up the 12v on A7 to the O/D relay.
I think that would work.

Let me know how it goes with the shifter and what problems to watch out for when I do my swap. I planned to use a Hurst Competition shifter. I don’t want to alter the console.
In addition, I saw in Summit or Jegs that Hurst has push button sifter handle to turn on and off any 12 volt item and thought this would work well for the 4+3 OD. I am not sure how to hide the power line to the OD though
