WEll the motor and tranny in my truck are both tired and starting to die. The tranny- 700 sometimes shifts hard from 1st to 2nd and i got a feeling it wont make it till summer. And the 350 is burning oil pretty darn fast.

So im starting to plan and gather parts for when one of them quits on me. I have another 350 block in the garage that i could rebuild-my buddy's dad owns a engine machine shop. Then just have the tranny rebuild and toss them back in and be good to go. But this is my dd so im really starting to look at getting a 6.2 and dropping that in. I also have a 400 tranny sitting in the garage that i could rebuild and put behind the 6.2 so i wouldnt have to worry about wrecking the 700.

gears? tire size? what kind of driving do you do daily? highway? mostly in town? any plans on towing with it? need a little more information to say really.
 
Well i have a 30 mile round trip each day to work and back and of course some casual driving here and there, not much highway driving but i want it to be highway friendly.

As for axles-gears and tires im gonna regear my 14 bolt and put it in the rear with a shackle flip. And convert the front to 8 lug. Probably 35" tires and 4.56 gears.

stick with the 350/700 when you build the 350, build it to make boat loads of low RPM toque, then go with the 4.56s and 35s like you had planned. i'd keep your peak torque around 1800-2000

That sounds pretty reasonable.
 
When you rebuild the 350, spring for a 3.75" stroker crank. You can get a cheap Chinese Scat one for less than $200. There's no replacement for displacement, after all. :D
