Well, as far as the fuel chain goes this winter I switched out the stock intake manifolds and rubbers for the billet aluminums from newspeedy.com, deshimmed the needles, replaced 160 mains with 150's, and replaced the stock air mixture screws with the newspeedy.com thumbscrews. Although I know it would be best to perform mods of this nature separately I took advantage of seasonal down time to get as much done as possible.
