need a bit of bottom end

[Tri-Flo 99]

cant do a verter or headers right now, so i gotta do some little things, i really really want some bottom end so i can break em loose (i figured that 3.42s would help, and i can chirp a bit, but no smoke...:-( ) so what can i do- im thinkin either a jet stage 2 or a maft. im leanin towards the maft because i plan on getting a cam in the next year. what kind of gains could i expect? i could also do plugs and wires, is there anything else i can do thats not major? i took the spare out ot get some weight off the rear, and i could spin a fraction more.
