i have a built 904 with the low 1st and second gears on standby.Plan was to put it in my dart and go with 2.94's First and second gears would be the equivalent to a standard trans with 3.30 rear gearIf i leave the 3.23 in it will act like 3.60 rear through the first 2 gears.
...2nd to 3rd is not a huge drop especially with a short duration cam having lots of lower rpm torque.
Such a great idea... don't know why it isn't more common?

I’m looking to do something similar to my 904. I have a slant 6. I’m calling a bunch of repair shops here in northern Cali and can’t find anyone with the knowledge or the know how to install what I want. The one guys that does have the knowledge is charging me 1400 for a bench rebuild. Does that sound like a decent price? That’s New bandz, clutch plates, steels. I want a mild or stronger shift kit installed if possible. Also looking for the stall converter to be 2000 rpms. 2.76 gear ratio or higher if possible. I’m just looking for a fair price, but I don’t really know what that looks like. And suggestions if any would be helpful. Thanks
