Tightening it won't help in my opinion. Slip just means you don't have enough distance to allow it to couple up, not that it's too loose. Doug Ok thanks Doug, that's exactly the kind of info I needed. Also saves me from pulling the trans and converter and spending money.

I now have a grand total of 5 passes on the car with 3 trips to the track, added some weight with a mild steel 6point roll bar and harnesses. Still haven't had time or energy to do any real tuning but better air and dropping the jets down 2 numbers netted a nice time slip: 1.51 60 foot 6.78 at 100.99mph 10.69 at 124.65mph Drove it to and from the track 50 min away, and yes I'm having a blast with it! Still need to do more jetting, haven't touched the timing, and I have several things to do such as sealing the hood scoop, slightly tighten the converter that has 17.5% slip, and might try a good electric water pump. The 3.23 gears will stay forever. Hey I thought you were going to come try my 26"s next time out after the cage install. Glad you got her out one last time. Are you sure on the slip numbers?? Heres my math for your latest mph outing with the 28" tires and if you would of used my 26's. 124.65 x 3.23 x 336/28 = 4831 RPM. 124.65 x 3.23 x 336/26 = 5203 RPM Not really that much different really but in the right direction. My combo at that MPH would be at 5998 RPM. You stated you were crossing the stripe near 5000 RPM, I don't see any room for 17.5% slip.?? Mike I should have text you, I replied to a thread on Moparts that you were on, and I mentioned that I want to just stick with the drag radials but you may not have seen it. On my 3rd trip to the track I finally remembered to look down at the tach and to my surprise it's crossing at exactly 5800. I looked at it 3 passes in a row. 1970 Challenger, all aluminum 528 Hemi, HDK suspension, Tremec 5 speed manual
