About 10-15 tops. I have the same set up with edelbrock base. You'll feel some torque too

You will really feel the ported intake, trust me! I had the SLP runners and ported stock intake and it was great. I've since upgraded to the Edelbrock intake.

My bad artic, you'll probably make more like 20 hp. I failed to see that you had headers and catback. One thing complements the other.

If you need someone to help you port the plenum, let me know. I'm port matching plenums to SLP runners as a way of defraying the cost of the hobby. In acttuality, my monthly net probably only covers me heating for the garage!
