Are your throttle plates opening completely at full throttle.
What size tire did you use out back this time? You probably would benefit with a little more converter, but I wouldn't overdo it if you drive mostly on the street. I like a happy medium that performs well on AND off the track.
Are you now sure you are getting full power? I had a similar issue and it was timing. After testing I ended up adding 4 more degrees and it made a huge difference. Mine ran fine and never skipped but just felt like less power up top than there should be - at first I was questioning the cam as it seemed like a stock 4500 rpm unit. With the added 4 degrees it pulls up to 6k now and I do intend to add more timing when the weather breaks. I only have 1k miles on it so far. I have read a lot about this and many engines like more than the 36 recommended by the 'general rules'. I'm at 38 now and do intend to add more when I start driving it again. In my experience, lean fuel issues cause backfires/misfires and zero output issues. If it's running smooth but has low power at rpm, it's probably a lack of timing at WOT@rpm. Your plugs could also show a lean issue. I have spoken to many that run 40-44 degrees without vac.
Sure made some improvement with the changes!
Put a good converter in that car and you are in the 12's easy. That Camaro was pretty soft out of the hole.
Definitely agree with muscle car on this. It was soft coming off the line.
