LS Swapped C10 Power Issues

[Joyridin]

I am going to assume it must have a pretty mild cam with only a 2200 converter in it...or maybe it doesn't have enough converter, which is part of the problem?

As stated, I would start with a tuner and go fro there. I know in both my truck and car, neither one of them really wake up until 3500, but I have pretty big cams in both. The truck will still spin the tires off the line, but when it hits 3k and above, it is like a totally different vehicle!
