The car should click that # like nothing. 4.56 gears may be a little much for a 360 in a light car. My car ran the same time with 3.91's as it did with 4.30's. For what its worth, I ran 12.90's at 104 with a 360 that had 340 Jheads, dual plane intake, 750 dp holley, and a .484 lift/284 advertised duration cam. Had a 3000 stall and 3.91 gears (I drove it an hour to get to the strip). Raced it as I drove it, full exhaust, etc. Your project sounds much more healthier than my 1000 dollar motor. Good Luck!
