I have an Eddy performer Dp manifold on a .040 mildly built 360 truck motor. It is a spread bore and I installed an adapter plate to fit a Holley 4160 square bore and it seals fine. With this setup I was able to get just under 15 sec at the 1/4 mile track. I was hoping to get closer to 13 on my next visit to the track.
Now, I have a brand new in the box Demon with all the fittings I need to install it on my fresh 360 sitting on the shelf. I noticed there is a vacuum leak somewheres in the intake causing a stumble at low RPM and I am thinking of changing out the Performer for an Airgap at the same time. Will this get me the 2 secs I want, or should I just leave it alone?
