stock GM T5 won't live long behind a 400. You'll have to upgrade with higher alloy gear set and other parts witch are harder to find over the ford T5 that I built-up for my nova. Or use a TKO 500 or 600, or an RS T-45 5-speed from Keisler that is about the size as a T5. http://www.keislerauto.com/vmchk/gm...a-5-speed-rs-perfectfit-kit/flypage_tabs.html
Like any rail type shifter trannys, you'll have to cut and raise the back of tunnel.
