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

Okay , sorry for not updating. Life issues have been keeping us busy on this end.Here's where we're at. We decided to change the converter after talking to a lot of people. So, we pulled the motor because I also wanted to degree the cam. When I pulled the timing cover, I found a chain that had what I would call excessive play for the amont of run time that it has.I ordered a roller chain and gear set with a 9 keyway crank sprocket and used that instead. It's tighter than the one the machine shop installed.While I was playing around with the cam, just for the hell of it, I slid both crank sprockets on with both of them with the dots straight up . On e of the sprockets was a 1/2 tooth off from the other. So my first question is, which one's lying???I ended up using the new timing set that I bought because after degreeing the cam, it seems to be right. The motor is back together, going back in this weekend. We have also decided to run a MSD box as well as go to a Holley Blue electric fuel pump and 3/8" fuel line.Hope to have it ready in a couple weeks for the track test and tune.
