Go for it,especially with higher RPM performance,it will only help. The HEI system is great,but it tends to break up and work like crap above 4,000 rpm. I'd ditch the Feedback Carb while i'm at it too. I'd also read "How to Build High Performance Ignition Systems" by Todd Ryden. The author is an employee of MSD and the book is written great. He suggests adding an aftermarket ignition module and coil to the HEI,and make sure you have a solid 12-14 volts going to the coil through at least 14 gauge wire.
