HEI VS. MSD 7AL-3
has anyone ran a 9 second car with a HEI then switched to a MSD7AL-3 my question did you pick up et with the MSD?, does the MSD use a lot of power? i have a friend that uses a HEI and does not have to charge between rounds, my msd is a older model and i run a electric fan, procomp electric water pump, mallory fuel pump, alternator & optima red top battery, i have to charge after every run i just bought a Sears charger (charges at 40 amps) seems to take a long time to get 100% charge. thanks for the help Doug
