Ok, so I just found a 98 and 99 pow. specials, bolth sleds w/ trailer for 3100. The ad doesnt say engine size, were they all 600's? No mention if theyre efi either, I know some were, but were they all in those years? They look real nice in the pics, I just left a voicemail on the guys phone, asking if he wants to swap my car thats up for sale, hopefully he will call back tonite or tomarrow. But for now could you guys give me a little schooling on these sleds? Thanks alot!
