Well I would use an MSD 7AL with dual stage retard . Most Honda guys just tune it for the motor and pull back the base timing on the dizzy for a single stage . Not too many have the balls to do a real dual stage ..


You can run a single stage retard box and just tune the car for the 1st stage if you want . I wouldnt put much timing in it depending upon spray amount and ramp time etc ..

Give me a little more info on your setup and i'll let you know how to better go about it
