I'm running EFI, so I had Mike Burns modify this to accept the Jaguar cap and modified rotor. The dizzy gives ignition signal as well as CAM sync for full sequential injection. Only other thing I could do is upgrade to a newer system and run COP's. But this system runs flawlessly over the last 20+ years. Hard to beat a proven system. Unfortunately it's no longer made. Holley bought them out and started making their own systems. Time will tell...
