Tossing around ideas in my head, involving a 5.0 (or why not dream big - ...) in front of a C-4, or possibly a C-5 (better torque converter, valve body, additional clutch packs) using C-4 adapters ( I don't need overdrive). C-4 bellhousing adapter would allow for bolting the C-5 to the SBF.
C-4/5 has a different output shaft than the 700r4 (28 spline vs. 27 spline), so I'd have to replace the input gear on the Atlas, or maybe custom out put shaft on trans. Drivetrain length would change, so more driveshaft mods. There is no adapter for my current transmission (60 degree 700r4) to a V8 of any kind, unfortunately, so a trans replacement would be necessary regardless. One option for replacing the input gear on the Atlas is a Blackbox-i.
Or I might just cut up the floor, install the larger 700r4, and run a 4.3 V6.
