Not Ranked
cheesehead,
The process is the same regardless of SB100 or trying to pass smog. I took my car in and tried to pass while waiting for Jan2 to get SB100. I've got a Roush 427R, which is a 351w Dart block. My smog referee tested it based as a '69 351, which is the first year in their books for a 351. I failed miserably. At least double the allowable emmisions, no heat riser, and the carb wasnt on the 'green' list of approved carbs. If you are going with a mild motor I think a 351 could pass. an early 289 or FE would be easier you shouldnt need the heat riser going into the carb, but they will still make you pass the tail pipe sniffer. Not impossible, but you'll need a fairly mild motor. Oh its my understanding that regardless of the year of the motor (say for example a 62) you still have to pass a sniffer test. If the block is older they will use the first year on the books I think that's 65, but not positive.
