Last Special

Can a pre-bent (unwelded) 10 point roll cage be assembled/installed in a lightened 1978 C3 without lifting the body off? Any guidance would be very much appreciated. I was thinking of an Art Morrison cage, and planning to get into the high 8 second range in the quarter with a 638ci Dart block, a performance TH400 and a Ford 9 inch with a spool.
