I agree with the SV intake. If Indy is charging $900 for the 440-3 then switch to the Edelbrock Super Victor. It is only $538 and you won't have to pay shipping. The SV intake works just as well as the Indy intake, if not better. On my 514 I switched to a SV intake and picked up power but I won't claim that it is always that way.
