some of the modern comments crack me up,

four large i.e 800cc injectors on a 500 plenum for over 500 bhp dates back to 1987

air injectors on the rs500 date back to 87 as well,

and as do though studding the block with ten studds from 87 again,

so it seams it all comes back, and then is called modern so wheres the new ideas then,
