So my only solution is buy an LS camaro ooorrr,put an LS in my old mopar.??? Gotta be another way to have something that fast, but cool too. Almost went 440 or 451 but son in law has a very fast LS camaro swap with a 6speed. Stupid fast with only cam, heads, and long tubes. I helped him build it. He also gets mpg in the low20's. It's a nice car but I like my mopar.... Gotta be a way???.....
