Replacing a 700R4 with a 4l80E in a 68 Camaro.

[Rileys68Camaro]

What will I need to swap my 700R4 out for a 4L80e and what am I looking to spend?

The 700R4 is just there, has a flexplate on the motor, not really installed and functional, started with it several years ago, before I heard of the 4L80e or this website.

Just looking for a decent junkyard find for now, to run a mechanical speedometer. Plans for a Shrifter(sp) in the future.

Small block 350, 300hp or so, 3:73 or 4:10 rear depending. I don't have any linkage or anything and thought before I went that way, I'd check into a 4l60e or 80e.

Don't have much time to search being deployed,and trying to get as much info to get my car driving as soon as i can when I get home.

Thanks!
