You got a Rat in it, do you run one or two bowls or the throttle bodys. I'm getting ready to have a nitemare, with my s/blk blown motor, i melted down a piston by not running down nozzles, now i'm going back with down nozzles and i'm sure it's going to take some working thru. I've got the K valve on it. It's Buzzard on top of a 1471 it was fast for a 358" but going back with a 383" motor.
