I'm guessing that first time out will be mid to high 13's and with tuning and practice, you can probably break out of the 13's. My Dad's malibu had a similar cam and 355, and ran mid 13's on street tires. when we went to a 383 we have just made it out of the 13's, still on street tires, 3.73 rear, posi and 700r4.
