TBI doesnt use HEI, and neither does the CFI that is on your new engine. HEI is a "coil in cap" ignition that was on engines prior to TBI. A TBI distributor will have a hall effect switch and a separate coil, and the CFI will just have an angle sensor for the PCM.

if you want an HEI, you will need to buy one.
