s400 on a 540?

[540Malibu]

will an unmodified s400 ( 76mm? 1.32 ex?) flow enough for 1000hp on a 540 at 6000rpm?

maybe, if i were you i'g go a little larger, or a little smaller and run go the twin route. twins 67's would make killer power and spool up in no time.

No it is too small.

1. It will not be able to feed it.
2. It will choke the exhaust also.

A pair of those could do it.
We sell them.
