Motor out of breath by 4,400, eh? Performer not designed to do much better than that, and stock iron heads are boat anchors. Don't blame the Demon just yet.

Get a pair of AFR185's, or TFS TW Street heads. Then bolt on a Performer RPM or Air Gap intake. Put the Demon back on, and then tell us what you think.

Definately hang on to the Demon 750 if you go the 393W stroker.

I have a Demon 650 on a 351W and love it.
