Something is WAY off there. I have the same cam in a very similar combo…410 stroker, 10.8 comp, ported eddys, Air-gap, 750dp, 4.10 gear…only mine runs 6.90’s @ 98mph in the 1/8 with a 1.49 60’. In the heat (90°F with lots-O-humidity) my car only slowed to a 7.08 @ 97mph. This cam make a lot of torque, so I doubt your gears are hurting you that much.

IMO, if you used the spring recommended by comp (914-16) then that may be part of your problem right there…those springs are too light. I’m running comp 939-16 installed @ 1.85, which gives ~ 190 lbs on the seat & ~460 lbs open. You should probably use more spring than what I have, I’m just limited due to my rockers.
