Had racing engine builder build my 383, lots of upgrade, forged, ported, 58mm tb, cam,...

Also upgraded from non vented to vented opti. Motor is back in car, motor turns over, but no spark. Everything looks like it's connected correctly. Getting power to coil, no spark from coil, coil worked with old motor.

Is it possible the Opti could be the problem? Any ideas on how to test to make sure New Opti was installed correctly?

Appreciate the help!
