Lock out the distributor mechanical advance curve. Set the now fixed locked out timing to 36deg BTDC.
Now reset the carb. It will idle around 1000 rpm. use a 3" or 4" rated power step up spring in the carb.
This cam need a full 36deg locked idle timing to idle correctly with a auto trans.
Get some 4.56's
Hint: instead of trying to "Hot lash" the valve lash set it cold at .022" instead of .026" hot.
