Ok, I'm looking to put a bullet into my elky soon...350, injected, shootin for about 325 hp or so...just something mild, I'll save wild for when gas goes down, or a get a milage car...whichever comes first.

My question about the tranny is this:

which tranny should i go with? it currently has a th350 that needs a rebuild...I have an extra 700r4 chillin in my garage...

I can do 1 of a few things...
1) Build the th350 back to stock with a mild clutch upgrade...
2) Build the th350 so that its bullet proof
3) Build the 700r4 to stock with a mild clutch upgrade...
4) Build the 700r4 with 4L65 parts to make it a bullet proof with a good low gear, and the overdrive to help me with gas milage...

Let me know what you guys think! I'm REALLY in need of advice because I can't decide...They all sound great to me!
