OK, Cars up and running again, not quite as strong as I thought it should be. Checked out the voltage, barely 11 vlts. Forgot about stupid underdrive crank pulley- . Just put OD pulley on alternator BIG difference. With elec wp, fp, fan, accessories on batt stays above 12 even at idle. Anyone been through this? How much did you have to change on your tuneup? ie jets, timing.....
Thanks
How much did it help you et/mph?
