Need help from some pros

Although I'm just a bracket racer I thought maybe some of you professionals could help me out. All of a sudden my car has slowed down. 2 weeks ago I was going consistent 8.18's,8.19's in the eighth mile. Last week car started going 8.40's, 8.39's with almost 3 mph loss also. So I thought , maybe the track, air, etc. you know the deal. Last night car went the same 8.45,8.42,8.39, still down on mph also.
First round I dialed 8.38 figureing I could just run it out and still be good with no worry. Well I broke out with a 8.372. Is this car telling me that it's too rich and wants to run faster as the night gets cooler?
If I advance the timing 2 degrees will this lean it out a little and tell me if that's the case, or do you think something else is going on here? It's a 454 motor with the timing set at 35 degrees right now.
Any help is greatly appreciated. I'm beside myself with this problem. Thanks-Russ
