cool, go with a cat back of your choice, delete the cats(a must), get sims to take car of 02's , go with bellanger or mopar long tubes(personally like bellanger) a CAI cold air intake of your choice,msd wires,(better tranfer of voltage) a good open throttle body,or port the stockone,add a 170 thermostate,use a good 5w30synthetic oil,buy the vec II from Jimmy(freakin killer deal they sell for $1000) and you should be all over 480rwhp!
Add a good gen II cam and later do the heads($3500) and you should be dead on or over 500hp.. The secret will be the dyno tune,find a good tuner in the area, which is where?
