I ran a Crower 34416 .21 inches of vacuum,same engine you basically have. 18 degree initial,34 total timing .. (cam specs were 284 advertised,224 at .the 50,and .481 lift with a 1.6. Idled like a stock 340 cam cold,with no choke ,double pumped. Look at Oregon Cams,for something similar, or give them a call.
