In the process of removing 326 out of the '66 Lemans convertible and installing the '71 455 . I had intended on leaving the stock electrical system in place, using the external regulator, as it worked flawlessly. However, the 455 came with a new hi-output alternator, with a built in regulator. if I used the new alt., how exactly would I bypass the reg. on the old system? What other variables would there be? Is it even worth the hassle? If not, The old alt. fits like a glove in the 455 brackets, so no big deal. Thanks.
