A-Team Performance - HEI Complete Distributor 65K-Volt Coil, 8 Cylinders - Compatible with BBF Big Block Ford 351C 351M 400M 429 460 - One Wire Installation Blue Cap

The FAQ responses reveal that the distributor is not compatible with some specific engines and vehicles, but it has an electronic ignition, and its cap incorporates a coil and a module. It can be used with roller cam if the gear on the cam is like a stock configured cam gear. The customer reviews are mixed; some customers have found it fantastic and easy to install, whereas others have found the cap's edges to be rough under the electric harness plug in, and it not functional at all after installation. Others find that it is a little bit slower than expected but worth it in the end. Overall, the distributor seems to have both advantages and disadvantages. It is worth buying for those who want to eliminate tons of wires from the ignition module and coils, but those interested should note that there are some compatibility issues with certain engines and vehicles.
