HEI ignition for 66 389 With tri power
 

Yesterday i bought a 66 pontiac tempest custom with a 389 tripower. And from the research I've done your typical hei ignition will not work with my tri power manifold. So from what gathering my only option is an hei conversion kit, any recommendations on the best one for my car? And I noticed Mallory makes a hei dist called an ultra lite, since it is so much smaller then the Typical hei does anyone know if it will clear the intake manifold?
Thanks for your time,
Tyson
