Advancing cam one tooth

I'm no expert on camming and am trying like you to learn a little. What very little I've found out shows Advancing the cam should rock the torque curve back reducing the topend horse power but give you more bottom end torque. Retarding the cam should do the oppsite reduce the bottom end torque and increase the upperend horse power. If I remember right the peek torque for the 283's and 403's is around 900 to 1000 RPM's but the torque curve is very flat. Where we are govenored at 1430 RPM's stock we may not be running fast enough that advancing would hurt our uperend horse power and it may help it. But I'd question if retarding the cam wouldn't really be a big mistake if we aren't turning lots of RPM's. I'm not sure if advancing the cam one tooth isn't to much, you may need to make an offset key. I tried advancing the cam on one of my U's and didn't think that really helped but that U is in terrable shape. I did think it helped my Z when I advanced it.

I'm really wondering which way I need to go with the 800's cam. It's peek is 1100 I think and I can run 2262RPM's.

What I've been told on advancing or retarding the cam's the single most important thing you are doing is changing when the intake valve closes.

Hopefully someone with a little more knowlage will come along and help us both out.
