yesterday i was over at my neighbors, borrowing his torch to help undo a bolt. anyway he just built this race car, on a 68 camarrow body, tube frame, the whole deal etc. i guess he said his first day out it ran the 1/4 mile in th elow 9's at about 145. anyway i was looking at his aluminum floor, and was wondering if that would work in a street z. if you got heavy alum. and tied it into the tranny tunnel, firewall rocker etc, do you think it would work. or what if you were to weld in steel cross braces underneath. would this work or just be a big imprcticle mess, with no advantages?
