Okay so i have a 72 cougar with the 351c and powertrain from a 71 the 351 has 400 miles on the rebuild and the FMX has a fresh rebuild with a 2400 stall TCI converter.
I just had it tuned by a mechanic and it revs just fine in the driveway. Then when i try to drive it kind of chugs and if i dont gas through it, it dies. My first thought was electrical so i replaced the voltage regulator and tested the alternator and the diode was bad so i put on another alternator and have the same issue. I have yet to test it but i am wondering if there is something killing my alternators or am i chasing the wrong issue.
Both the alternators were working when i pulled the engines a couple months ago. Also i noticed that the wiring for the alternator was different from my 71 to 72. the 71 only has 2 wires but the 72 has 4 going to the regulator.
I have been thinking of converting to a one wire setup for the alt i am not sure if it will help.
Also when the engine was in the 71 i had a MSD box hooked for the MSD distributor but i have changed distributor to a non-controller required unit.
Is it possible that it is the carb the 71 sat for about 6-8 months without running?
Any ideas are welcome
