Iam so glad I didn't go with 410's. The 456's make a big diff, left rubber patch hitting second gear and didn't see the cop on the corner but he saw me lol. Thank god i knew him from my old shop no ticket. changed gear setting to 456 with my superchips tuner, now just need to mess with shift points alittle. Now thinking of a cam also.. The 456 don't have neck braking action and thats why Iam glad with the choice of 456's. Have to let them heat up and cool for a few miles 40-50 my tech said, then I'l see how well they do?
Oh yeah not one peep out of the rear end either..
