Ok so I have started going through this 77 f250 highboy, and yes its a true highboy lol but lets not get that started again lol Anyhow I am pulling out the tranny for a rebuild what knowledge do you fellas have to share to make it "bullit proof" any suggestions or comments would be greatly appreciated
Its going behind a 400M with the edlebrock power package right now but there is a 557 stroker with lots of laughing gas in the works that will probably be installed within the next year so I want to build it now rather than after as its a little sloppy now. Looking for suggestions on valve body, mods I can do myself and I believe I even read on here about some parts I could take out of an E40d to improve performance, etc. As of right now the truck has no lift but is on 35" TSL's has A low pinion D44 in front and A D60 in the rear with 4:10 gears. which I plan to change to 5.13's or something in that area. And a divorced 205 t case which I also want to go through. I intend to put a D60 up front eventually and weld up the rear. As for usage it will be for mud pit runs and a whole lot of just tearing up my back 60 acres.
hope this is enough specifics if more info is needed please let me know as I will gladly provide it

some guts out of a AOD or E4OD guts into the C6 give you lower gearing.f

Just for those not in the know, I thought I'd second this ;)

What are your plans for a converter? It's not going to be easy picking a converter that will work for both motors.

I really havent gotten that far into the 557 to have chosen a cam yet so im not ready to commit to what size converter ill be needing for it. Per PRO's instructions, I will start a thread for the build once I have all the parts to build it but I dont want to keep you guys hanging while I wait for money to buy the parts, as I recently blew out my shoulder and well workmans comp is a bitch to make a living with and build a play toy. I bought a 75 F-250 today and I will use the 400M and what ever converter I end up with for the 400 in it once the 390 is feeling weak so thats no big loss as the 75 has a 390 with a 4 spd in it and im not a big fan of manual trannys(I tend to get a little gas pedal happy and over rev) it gets expensive real quick

does the aod or e40d guts give any strength or is it just gear? i am lookin at the 557 too. the converter will be a whole lot of guess work, gotta love gambling.
