im thinking something along the lines of a Camaro Front Subframe,Truckarms,
throw out everything that doesnt make it go faster,lexan and just enough safety junk to pass tech.Of course usually A HUGE Big Block would be the choice but i was thinking of something like a turbo 6.0L vortec backed by a jerico 4 speed or a tko-600,i guess you could just build the frame from scratch because i dont think using the stock one even with a million lightning holes is gonna weigh as little as a tube one....just throwing some ideas out there
