They said you need a crank signal but didn't mention what they did to use one. I run an LA motor with a std 904 so no provisions for sensors on my combo.
They need a TACH signal....not a crank trigger.... You just need a MSD or MSD type distributor with a phasable rotor in it VS stock. There are very few of these on vehicles with crank triggers. Again you just need the proper distributor.
