At 707hp and what weight? I have one on the shelf that would live with the right clutch...for a while.

edit: I see the 3600 lbs.

You would be better off installing a G Force 4-speed IMO. I have a "fall race" (not 3/4) face plated, 9310 geared unit with an aluminum case, billet this and that, etc. IMO it's limit, with longevity in mind, would be about 650hp at 3600ish lbs. More power or weight and you need to look at at transmission with wider, straight cut gears.

That said if you don't dead hook it a face plated a-833 might lat for quite some time. My situation (750hp, 3550lbs) made me nervous (and lazy) so I went with a GF5R which is rated to 1400 at 3400 lbs.
