Your runs are very similar to mine.The 410 I have has oodles of torque down below,as I had issues hooking also(mph was all over the place).What slicks,sizes are you running?I,m now gonna run a 28 inch slick,take my exhaust off,swap to a 4.30 gear with spool.Hoping to see 10,s soon.:clock:
those runs are on a M&H DOT 325/50/15 27 1/2 to 28" tall 4.10 gear through exhaust. i didnt notice any traction issues until the final run. (but did a terrible burnout)
