360 does not seem to be making power and is slow in the 1/8. Need help and/or suggestions

@12many yep, it runs bad and it's the converter. A fricken stock converter in that car should run 1.75-1.80 60' The tune is MILES off...

Ok guys thank you for all of your help so far! Sorry it took so long to respond, things have been crazy on my end!
So here is an update, we found something goofy with the distributor that seemed to be making the car flat. The last person that had the distributor before us must have been screwing with it and the plate that held the pickup coil was actually loose and had the pickup coil in all different spots, sometimes really close to the sprocket and sometimes not touching it at all. Just for kicks; we had a stock distributor that we had a stock distributor around with one large spring and one thin spring. We took the large spring out and left the thin spring in just to see what would happen. The 60 foot didnt change too much but the car picked up almost 2.5 tenths. the car went 8.80 at right around 80mph. All that was changed was the distributor. Since the 60 foot still stayed the same im assuming it will be a converter change over the winter to make that improve. It was around 2.05 again, so I have to guess that based off my research that it will need to be mid 1.50s-1.60 60' to get mid 7s. Just wanted to give an update; hope this helps in any way
Why blame the parts? Just for an example, my Duster with 2.94 gears, 100% factory stock converter and with a basically stone stock 360 and stone stock cast heads cut a 1.86 60 ft and ran 8.40's in the 1/8 (I've since swapped heads). I posted this so you can see how far your tune is off. Why do so many just throw money and parts at their build till they get the ET they want. Tune tune tune..... Your combo should blow mine away!! TUNE!!!!!!!! there, I'm exhausted... LOL :D
