Been down the ICE track before thanks.

Bob, my engine is developing over 610bhp at 6800rpms. sounds like a good distributor should work for those rpms. ECU are you referring to e.g. MSD 6AL Programmable ignition box or an MSD 8979 multifunction ignition controller.....?

Crane make a Pro Curve distributor with different electronic advance curves which looks good.
