considering swapping out my 355s for some 410s, just curious if they would hurt me or help me. my car is a very mild 347 with a tko 500. with the 355s i'm still in 3rd gear through the 8th. will the 410s cause me to shift into 4th at the finish line and hurt me? it has been 8.51 at 86 on street tires 275/40/17 with a 2.1 sixty. on dr has been 8.01 at 88 with a 1.81 sixty, both runs was on a 355 gear and a t5 trans. i cant remember what rpm i was at crossing the finish line cause i havent raced in 6 months. i shift at around 6k-6200 thanks for any help.
