    you cant hurt the stock motor with a winpy x charger
    you need to check your valves to see if they are the good ones

    what octane fuel do you use or will use?
    because if you can use good fuel you dont need low comp pistons
    stock rods IMO will do 350hp all day long (20psi)

    is your octane the same as ours (R+M)/2
    94 ron octane is 89 here
    if that is the best you can get then stay with 8.5:1 pistons
