Performer vs RPM?
What's the real difference between a Performer and a Performer RPM on a street driven 390 Mercury? I got a free Performer and read nothing good about them. Are they better than a stock 4bbl intake, or just lighter?
Dammit, another good ol boy gone. Condolence to the family. RIP Mike
