Ok im building my 347 and need it to be emissions legal. I am geting afr 185cc emision legal heads also. does anyone know the biggest cam i can run and still be emissions legal? who is the best custom cam grinder i can talk to about this? is it still possible to reach high 300's N/A and be emissions legal? also this is all on my stock block too. i want to give it mabe 6-8 pounds of boost later on down the road as well.
