Some guys on the Impala forums actually passed with the 846 cam in a 355 or 383 without touching the computer. It was a little on the rich side, but it still passed. After some proper tuning they're very clean. Not sure why its so different between the LT1 and the Vortec... unless he did it on stock heads. If his heads were stock it might have made things a tad rich, or if his knock sensor started pulling too much timing out. Those things have been known to happen.
