Here is some more food for thought:
This thread prompted me to dig out some old mag issues looking for the old Edelbrock ad that claimed 37 additional hp from their Performer intake. (Well, I found it. Next problem is getting this cleaned up before my wife gets home. I've got enough old magazines on the floor for a foot tall stack for every crapper between LA and New York)
In the 8/96 MM&FF page 59 Edelbrocks advertisement reads that they gained 37 hp on a stock engine with a Performer Intake 70mm TB, an EGR plate and exhaust. That was on stock heads.
Will that make 3 tenths and 3 MPH difference? I think so. I know the intake was not an Edelbrock, the example just serves as a reference. Congrats on the 13.9.
As for which intake to run, I like the Holley II.
