440 with slant 6 torsion bars

Im running a 383 with headers, alum intake and and no a/c with the 340 bars. Like 72 said its not that hard to get a big block to weigh what a fully optioned small block does using some aluminum. I think my 71 handles great with those bars but I've also got KYB's up front and a 1 1/8" sway bar.
